Biomusic

Biomusic is an interdisciplinary field that involves the generation of music from biological data, processes, or signals, often through sonification techniques that convert physiological or environmental inputs into audible musical elements.^[1] This approach encompasses the translation of human autonomic signals, such as heart rate, respiration, skin conductance, and temperature, into melodic, rhythmic, or harmonic structures, as well as the use of non-human biological sources like microbial activity or natural bio-environmental sounds.^[2]^[3] Emerging from the convergence of biology, musicology, and technology, biomusic challenges traditional notions of composition by emphasizing living systems as co-creators of sound.^[3] The origins of biomusic trace back to 1986, when the term "BioMusic" was coined during a biodiversity conference at the National Academy of Sciences in Washington, DC, bringing together scientists, musicians, and artists to explore music's evolutionary and communicative roles in nature.^[3] Early developments focused on understanding music-making as a biological process across species, including non-human animals, to reveal how sound facilitates relationships, meaning-making, and cultural evolution in living systems.^[3] By the early 2010s, technological advancements enabled real-time interfaces, such as those mapping electrodermal activity to melody, heart rate to percussion, and respiration to ambient effects, transforming abstract physiological data into expressive music.^[2] Key applications of biomusic include therapeutic and communicative tools, particularly for individuals with profound disabilities or autism spectrum disorders, where it sonifies emotional states to aid caregivers in interpreting anxiety, relaxation, or engagement without verbal cues.^[2]^[4] In ecological contexts, it generates music from non-human sources, such as bioelectrical signals from algae or bacteria in biophotovoltaic systems, promoting awareness of environmental dynamics and sustainable sound art.^[1] Ethical considerations arise in its use, including consent for physiological monitoring and the risk of misinterpreting translated signals as definitive emotional representations.^[4] Recent innovations continue to expand its scope, integrating biofeedback for wellness, education on biodiversity, and interdisciplinary research into the cognitive foundations of music across life forms.^[3]^[1]

Definition and History

Definition

Biomusic is a form of experimental music that involves sounds created, performed, or derived from biological sources or processes, including both human and non-human origins. This encompasses natural acoustic phenomena, such as the vocalizations of animals and other organisms, as well as the translation of biosignals—data from physiological activities—into auditory forms.^[5] The term "biomusic" originated from the BioMusic Program, initiated in 1986 by Patricia Gray during a biodiversity conference at the National Academy of Sciences in Washington, DC, to explore music's role in nature through interdisciplinary collaboration.^[3] Ornithologist Luis Baptista contributed significantly to the field in the late 20th century, emphasizing parallels between animal songs and human music through his studies and analyses of natural biological sounds.^[6] Baptista's work highlighted the musicality inherent in non-human species, bridging biology and artistry. A key distinction of biomusic is its emphasis on biological origins, differentiating it from traditional human-composed music without biological inputs, while including both unaltered recordings of biological acoustics and creative processed interpretations. Scope variations within biomusic range from acoustic forms, which draw directly from environmental sounds like biophony—the collective non-human organismal sounds in a specific habitat—to biosignal-based approaches that map bodily data, such as heart rate or brainwave patterns, to musical elements like melody or tempo.^[7]^[5]

Historical Development

The roots of biomusic trace back to the 19th century, when scientific interest in bioacoustics began to emerge alongside early efforts to capture natural sounds. Charles Darwin's observations in On the Origin of Species (1859) highlighted bird songs as examples of instinctual behaviors shaped by natural and sexual selection, laying foundational ideas for understanding vocalizations in evolutionary contexts. By the late 1800s, the invention of the phonograph enabled the first recordings of animal calls, such as Ludwig Koch's 1889 capture of a captive Indian shama's song at the Frankfurt Zoo, marking the onset of systematic documentation of non-human sounds.^[8] The term "biomusic" was formalized through the 1986 BioMusic Program at the National Academy of Sciences biodiversity conference, led by Patricia Gray, which brought together scientists, musicians, and artists to examine music-making across species.^[3] Ornithologist Luis Baptista, a leading expert on bird song dialects, advanced the concept in the 1980s and 1990s via his studies at the California Academy of Sciences, where he explored parallels between avian vocalizations and human music in museum displays and publications. This culminated in the 2000 BioMusic Symposium at the American Association for the Advancement of Science Annual Meeting, to which Baptista contributed planned lectures before his death in 2000, examining musicality in nature through presentations on whale songs, bird calls, and more, as summarized in a 2001 Science perspective. Mid-20th-century avant-garde composers further bridged bioacoustics and music; notably, Olivier Messiaen's Catalogue d'oiseaux (1956–1958) incorporated transcribed bird songs from field observations into piano compositions, influencing experimental music's engagement with natural sounds.^[9] The late 20th century saw a shift toward biosignal translation, with early biofeedback devices in the 1970s enabling real-time conversion of physiological data into sound. Pioneers like David Rosenboom used electroencephalogram (EEG) signals to generate music in works such as Portable Gold and Philosophers' Stones (1972), integrating brainwaves from performers into interactive compositions.^[10] Post-2000, digital advancements accelerated this evolution, with affordable software and sensors facilitating real-time physiological music generation, as seen in systems mapping heart rate or EEG to sonic parameters for therapeutic and artistic applications.^[11] Key publications like Bernie Krause's The Great Animal Orchestra (2012) popularized biophony—the collective acoustic signatures of ecosystems—in music contexts, emphasizing soundscapes as orchestral models and inspiring interdisciplinary practices.^[12]

Natural Acoustic Biomusic

Biophony

Biophony refers to the collective acoustic signals generated by non-human organisms within a specific ecosystem or biome, forming a holistic soundscape that reflects the interplay of biological voices.^[7] This concept, coined by bioacoustician Bernie Krause in the early 1980s during his field recordings in Africa, emphasizes the biophony as an emergent property of the habitat rather than isolated individual sounds.^[13] Krause's work built on his earlier explorations of natural soundscapes starting in the late 1960s, establishing biophony as a key component of soundscape ecology.^[14] A defining characteristic of biophony is its layered structure, where sounds from diverse organisms—such as insects producing high-frequency stridulations, birds occupying mid-range vocalizations, and mammals utilizing lower frequencies—create a complex sonic tapestry.^[15] Central to this organization is the acoustic niche hypothesis, proposed by Krause, which posits that species partition the soundscape into distinct frequency, temporal, and spatial bands to minimize acoustic interference and optimize communication.^[16] This partitioning results in a harmonious, non-overlapping symphony that reveals the ecosystem's structural integrity and species diversity.^[17] To capture biophony authentically, recordings must minimize human intrusion and employ specialized equipment. Parabolic microphones, which focus distant sounds like an acoustic lens, are commonly used for terrestrial biophonies to isolate natural layers without amplification artifacts. For aquatic environments, hydrophones—underwater microphones—enable the documentation of submerged biophonic elements, such as those in coral reefs or river systems, preserving the original amplitude and spatial dynamics. These techniques, refined by Krause over decades, prioritize long-duration, multi-channel captures to represent the full temporal evolution of the soundscape.^[14] Unprocessed biophonic recordings hold significant musical potential, serving as ambient compositions that evoke the rhythm and texture of ecosystems. Krause's Wild Sanctuary project, initiated in the 1980s, has produced over 50 albums of such soundscapes, including dawn choruses from rainforests and nocturnal insect symphonies, which have been integrated into contemporary music works for their immersive, non-hierarchical qualities.^[18] These recordings demonstrate biophony's role as a source of generative inspiration, where the natural orchestration influences experimental and electronic genres without alteration.^[19] Ecologically, biophony functions as a sensitive indicator of biodiversity, with the density and diversity of its layers correlating directly to habitat health and species richness.^[15] Declines in biophonic complexity, often measured through spectrographic analysis, signal disruptions from habitat loss, climate change, and noise pollution, which fragment acoustic niches and reduce the overall sonic vitality available for musical and scientific applications.^[19] For instance, Krause's longitudinal recordings show that over 50% of documented biophonies have significantly diminished since the 1980s due to anthropogenic pressures, underscoring the urgency of conservation to preserve these natural sonic resources.^[14]

Animal Vocalizations in Composition

Animal vocalizations, as elements of biophony, provide a rich palette for composers seeking to integrate natural acoustics into musical structures.^[20] Prominent examples include the incorporation of bird songs, such as nightingale recordings, in R. Murray Schafer's seminal work The Soundscape (1977), where these vocalizations illustrate the acoustic layers of natural environments and their potential for sonic art.^[20] Similarly, Roger Payne's 1970 album Songs of the Humpback Whale captured elaborate humpback whale vocalizations, which profoundly influenced ambient music by demonstrating the melodic complexity of marine sounds and inspiring composers to explore oceanic themes.^[21]^[22] Composers employ various techniques to adapt these sounds, including sampling and looping animal calls to create rhythmic foundations, as well as pitch-shifting to align them with Western musical scales for harmonic integration.^[23] A historical instance in popular culture is The Beatles' "Blackbird" (1968), where Paul McCartney's fingerpicking guitar technique mimics the trills and chirps of birds, enhanced by overlaid recordings of sparrows and finches to evoke natural avian melody.^[24] Case studies highlight innovative applications, such as Pauline Oliveros' "Deep Listening" pieces from the 1990s, which incorporate marine mammal sounds like humpback whale songs into improvisational works using digital instruments to blend human and cetacean expressions.^[25] In modern electronica, artists like Pali Meursault utilize insect stridulations—rubbing sounds produced by crickets and beetles—in albums such as Stridulations (2018), layering field recordings with electronic processing to form textured, rhythmic compositions that highlight arthropod acoustics.^[26] Challenges in this practice include ethical considerations for recording, where methods must avoid causing animal distress, such as using non-invasive remote microphones during natural behaviors rather than playback lures that could elevate stress hormones.^[27] Additionally, copyright issues arise with natural sounds in commercial music, as the specific recordings are protected intellectual property, requiring permissions even for unaltered field captures to prevent infringement claims.^[28] The evolution of these integrations traces from 1960s field recordings, like Bernie Krause's early wildlife captures in In a Wild Sanctuary (1970), which pioneered direct sonic documentation, to 2020s AI-enhanced synthesis, where tools analyze and generate animal vocalizations—such as transforming bird calls into melodic motifs—to enable novel compositions without physical recording.^[29]^[30]

Biosignal-Based Biomusic

Neurofeedback Interfaces

Neurofeedback interfaces in biomusic utilize real-time electroencephalography (EEG) to monitor and translate brainwave patterns, such as alpha (8-12 Hz) and beta (12-30 Hz) waves, into audible musical elements like tones, rhythms, or harmonies, enabling users to influence sound output through cognitive modulation.^[31] This process operates on operant conditioning principles, where auditory feedback reinforces desired brain states, fostering self-regulation without invasive interventions.^[32] Pioneered in clinical settings, these interfaces bridge neuroscience and music by converting neural oscillations into expressive sonic forms, often for therapeutic or artistic purposes.^[33] The historical foundations trace to the 1960s, when Barry Sterman at UCLA developed sensorimotor rhythm (SMR) biofeedback using EEG to train cats and later humans, demonstrating that operant conditioning could enhance brainwave control and reduce epileptic seizures.^[34] By the 1970s, composer David Rosenboom extended this to musical applications, creating performances like Ecology of the Skin (1970) and the Brainwave Music series, where performers modulated EEG signals to generate and alter electronic music in real time.^[35] These early works integrated biofeedback with synthesizers, such as the ARP 2500, to produce improvisational compositions responsive to brain activity.^[36] Musical neurofeedback has since gained traction through protocols in audio biofeedback systems, which map brainwaves to melodic structures for clinical use.^[37] Key technologies include protocols that map theta waves (4-8 Hz), often elevated in attention-deficit/hyperactivity disorder (ADHD), to variations in melody or tempo, allowing users to "play" music by shifting from theta-dominant to beta-dominant states for improved focus.^[31] In ADHD therapy, such systems provide immediate sonic rewards—e.g., harmonious tones for increased beta activity—training neuroplasticity over multiple sessions.^[38] Modern implementations, like the Muse headband (introduced in the 2010s), employ portable EEG sensors to generate ambient soundscapes during meditation, where calm alpha waves amplify soothing melodies and reduce dissonance.^[39] These interfaces offer benefits such as enhanced neuroplasticity and emotional regulation, with studies showing improved attention in ADHD patients through repeated training and reduced anxiety through musical reinforcement of relaxed brain states.^[40] Recent systematic reviews as of 2025 highlight ongoing advancements in musical neurofeedback for clinical applications, including stress management and neurorehabilitation.^[32] They remain non-invasive, relying on surface electrodes for accessibility.^[31] However, limitations include the need for individualized calibration to account for inter-subject EEG variability, potential inconsistencies in feedback protocols, and dependency on user motivation for sustained efficacy.^[41]

Physiological Signal Mapping

Physiological signal mapping in biomusic involves the real-time or offline conversion of non-neural bodily signals, such as those from the autonomic nervous system, into auditory elements to facilitate monitoring of emotional or physiological states or to create interactive artistic expressions.^[5] This approach draws from the broader field of sonification, where data parameters are systematically translated into sound properties to reveal patterns not easily discernible through visual means.^[42] Common signals include electrodermal activity (EDA), which reflects sweat gland responses to arousal; heart rate variability (HRV), indicating fluctuations in inter-beat intervals; and respiration patterns, capturing breathing depth and rate.^[43] The development of physiological signal mapping emerged in the 1990s alongside affective computing, a discipline pioneered by Rosalind Picard that sought to enable computers to recognize and respond to human emotions through physiological cues.^[44] Early efforts integrated biosensors with audio synthesis to sonify these signals, building on biofeedback techniques from the 1970s but advancing them with digital processing for more nuanced musical outputs.^[45] By the mid-2010s, this mapping had matured into accessible tools for both therapeutic and performative contexts, emphasizing intuitive auditory representations over complex visualizations. Key signal types are mapped to specific musical parameters to convey physiological dynamics intuitively. For instance, EDA, often measured as galvanic skin response (GSR), is commonly sonified to melody or pitch, where increases in conductance due to sweat response elevate melodic contours or note frequencies, signaling heightened arousal.^[5] HRV is typically linked to tempo, with greater variability accelerating rhythmic elements like drum beats to reflect sympathetic nervous system activation.^[46] Respiration influences volume dynamics, where deeper or faster breaths modulate amplitude, such as through swelling "whooshing" sounds during exhalation, providing a tactile auditory sense of breathing effort.^[5] Additional signals like skin temperature may alter harmonic structure, shifting musical keys to warmer or cooler tonalities based on thermal changes.^[5] Techniques for these mappings rely on parameter-mapped sonification algorithms implemented in real-time software environments. In platforms like Max/MSP, GSR data is processed to generate melodic lines by scaling signal amplitude to MIDI note values, allowing for dynamic adjustments in pitch and timbre during live input.^[47] A seminal example is the 2016 Biomusic interface, which integrates multiple sensors to produce cohesive musical pieces from children's physiological data, mapping EDA to melody, skin temperature to key, heart rate to percussion tempo, and respiration to volume embellishments, all output in MIDI format for broad compatibility.^[5] These algorithms often filter raw signals—such as applying Butterworth filters at 256 Hz sampling rates—to ensure clean, artifact-free mappings suitable for auditory interpretation.^[5] Applications span therapeutic monitoring and artistic performance. In therapy, these mappings enable stress detection by sonifying EDA and HRV patterns, allowing clinicians to identify anxiety episodes in children with autism spectrum disorders through musical cues, with studies reporting over 80% accuracy in state classification.^[5] For live performances, performers' arousal levels—via GSR or respiration—can alter ongoing music, fostering immersive experiences where audience-performer biosignals influence tempo or volume in real time.^[47] Such uses promote emotional awareness without requiring visual attention, distinguishing physiological mapping from brain-focused neurofeedback methods. Technical implementation frequently employs linear scaling to translate signal amplitudes to musical frequencies, ensuring proportional and predictable changes. For example, an increase in GSR conductance might raise note pitch by a fixed Hz increment per microsiemens, maintaining perceptual linearity as per established sonification guidelines.^[42] This straightforward scaling avoids nonlinear distortions, allowing users to intuitively correlate physiological shifts with auditory variations, though custom thresholds are applied to normalize individual baselines for therapeutic reliability.^[5]

Technological and Cybernetic Biomusic

Cybernetic Systems

Cybernetic biomusic refers to closed-loop systems in which biological inputs, such as physiological signals, dynamically influence musical generation, while the resulting music feeds back to modulate the biological state of the participant or organism. This approach draws from the foundational principles of cybernetics, as outlined by Norbert Wiener in his 1948 work, which emphasized feedback mechanisms for control and communication in both mechanical and living systems. In biomusic, these loops create interactive environments where, for instance, detected brain activity can trigger acoustic responses that alter the performer's neural patterns, fostering a reciprocal exchange between body and sound. A seminal example is Alvin Lucier's Music for Solo Performer (1965), where amplified alpha brainwaves from the performer trigger percussive sounds from the performer's body parts, establishing an early model of biofeedback in musical performance. Key frameworks in cybernetic biomusic extend Wiener's theory to bio-artistic practices, integrating sensors that capture biosignals like electromyography (EMG) for real-time gestural control. In the 1990s, Atau Tanaka developed the BioMuse system, which used EMG to detect muscle tension and translate it into musical parameters, enabling performers to manipulate sound through subtle bodily movements without traditional instruments. This setup exemplifies a cybernetic loop by allowing the music to respond instantaneously to physiological changes, such as varying muscle contractions, thereby influencing the performer's physical engagement. Physiological signal mapping serves as a primary input source in these systems, converting raw biosignals into actionable data for musical synthesis.^[48] Interactive installations further illustrate cybernetic biomusic through non-human biological entities, such as plants, whose electrical signals are harnessed to generate adaptive soundscapes. In the 2000s, sonic artist Mileece created botanical music pieces where electrodes attached to plant leaves capture bioelectric transmissions, processing them into immersive, evolving audio environments that respond to environmental stimuli affecting the plant. These works form closed loops, as the generated music can indirectly influence the plant's surroundings—such as through audience interactions—potentially altering the signals in a feedback cycle.^[49] The core components of cybernetic biomusic systems include sensors for detecting biological inputs, processors for analyzing and mapping data to musical outputs, and actuators for producing sound or vibrations. Sensors, such as EEG electrodes or EMG amplifiers, capture real-time physiological data; processors, often software algorithms, interpret these signals to control synthesis parameters; and actuators, like speakers or electronic instruments, deliver the auditory feedback. This architecture ensures the system's responsiveness, with feedback loops maintaining dynamic equilibrium.^[50] A central emphasis in these loops is homeostasis, where the music acts to stabilize biological deviations, such as generating calming tones in response to detected elevated physiological arousal to restore balance. For example, if heart rate variability indicates stress, the system might adapt the musical output to promote relaxation, exemplifying negative feedback for regulatory purposes. Such mechanisms mirror broader cybernetic principles of self-correction in living systems.^[51] Post-2010 advancements have incorporated artificial intelligence to enhance predictive adaptations in cybernetic biomusic, allowing systems to anticipate biological changes based on historical data patterns. Machine learning models analyze ongoing biosignal streams to forecast user states, enabling proactive musical adjustments that deepen the feedback loop's efficacy. This integration, as seen in affective generative music-AI frameworks, transforms static responses into anticipatory ones, broadening the scope of human-AI-biological interactions in performance.^[51]

Generative and Interactive Methods

Generative approaches in biomusic employ algorithms to create procedural music dynamically from biological data, such as biosignals or simulated biological patterns, allowing for evolving compositions that mimic natural variability. One prominent method involves genetic algorithms, which evolve musical structures like melodies by treating them as populations of "genomes" subjected to selection, crossover, and mutation processes inspired by natural evolution; these techniques often draw from synthetic biology, where genetic processes simulate DNA recombination to generate musical sequences, as seen in the Genetic Music System (GeMS), which translates simulated biological evolution into audible outputs.^[52] Lindenmayer systems (L-systems), formal grammars originally modeling plant growth, have been adapted for biomusic to generate fractal-like musical patterns that reflect organic branching and recursion. In musical L-systems, rewrite rules produce strings interpreted as pitch sequences or rhythms, evolving iteratively to emulate biological development; Stelios Manousakis's framework, for example, applies parametric L-systems to create compositions that parallel the stochastic growth of natural forms.^[53] Interactive tools facilitate real-time biomusic creation by incorporating user or biological inputs into generative processes, enabling performers to influence algorithmic outputs dynamically. Software like ChucK, a strongly-timed programming language for audio synthesis, supports live coding with biosignal integration, where inputs such as electroencephalography (EEG) or electromyography (EMG) from muscle tension alter ongoing musical sequences through concurrent threads and time-aware scripting.^[54] Complementary toolkits, such as BioTools, provide modular hardware and software for composers to interface biosignals—like neural or muscular activity—with generative engines, allowing gestures like hand clenching to modulate parameters in procedural algorithms for improvisation.^[55] Historical examples illustrate early fusions of biofeedback with generative interactivity; Alvin Lucier's "Music for Solo Performer" (1965) used amplified alpha brainwaves to trigger percussive sounds from performers' bodies, pioneering interactive generation from neural biosignals in a cybernetic feedback loop.^[10] In the 2020s, virtual reality (VR) environments have advanced this by syncing user biometrics, such as EMG-detected gestures, to procedural audio worlds, where classified muscle signals drive real-time sound synthesis for immersive, adaptive compositions.^[56] Techniques like Markov chains predict and generate musical phrases from biosignal patterns, capturing probabilistic transitions to emulate biological irregularity. This stochastic approach prioritizes variability, using chain states to branch into diverse outputs without rigid formulas, thus mirroring the non-deterministic nature of physiological data. Innovations in mobile applications leverage smartphone sensors for crowd-sourced biomusic generation, democratizing access to interactive creation. PlantWave, for instance, connects plant electrodes to iOS and Android apps, translating bioelectric signals into generative instrument presets that users can share and remix collaboratively, fostering communal soundscapes from distributed biological inputs.^[57]

Applications and Examples

Therapeutic and Medical Applications

Biomusic, which translates physiological signals into musical outputs, serves as a core technology in neurofeedback interfaces for therapeutic purposes, enabling users to self-regulate emotional and cognitive states through auditory feedback. In anxiety management, biomusic protocols sonify brainwave patterns, such as reducing excess beta waves (associated with heightened alertness and stress) by generating rewarding harmonious tones when alpha or theta waves increase, thereby promoting relaxation. A 2013 study found that musical biofeedback allowed participants to modulate arousal levels comparably to traditional sonification methods, with participants reporting intuitive control over their physiological states during sessions.^[37] For post-traumatic stress disorder (PTSD), neurofeedback has demonstrated symptom reductions in clinical trials, with one systematic review reporting decreases ranging from 7% to 72% (median 42.5%) across studies, particularly in hyperarousal and intrusive thoughts.^[58] In medical contexts, biomusic facilitates bonding through sonification of maternal heartbeats, transforming signals into melodic patterns that allow parents to engage with their child's rhythms in a musical form, fostering emotional connections. Research on heartbeat sonification projects indicates physiological responses such as synchronized heart rates between mothers and newborns, supporting its role in early attachment.^[59] For stroke rehabilitation, biosignal-based biomusic maps patient movements—such as arm kinematics—to real-time musical phrases, encouraging motor retraining through rhythmic entrainment. A 2019 randomized trial showed that musical sonification of arm movements improved upper extremity function in stroke patients, with gains in motor accuracy during therapy sessions, and related music-supported therapies, including those funded by the GRAMMY Foundation, reported enhanced neuroplasticity and functional recovery.^[60]^[61] Clinical evidence underscores biomusic's efficacy in attention-related disorders, with neurofeedback trials for ADHD yielding medium to large effect sizes in improving focus and reducing hyperactivity, including sustained attention gains observable up to 12 months post-treatment. One review highlighted improvements in cognitive control, with participants showing better performance on attention tasks after 20-40 sessions. Ethical considerations in biomusic applications emphasize informed consent, ensuring participants understand signal processing, potential privacy risks from biosignal data, and the voluntary nature of engagement, as outlined in neurofeedback guidelines.^[62]^[63] Emerging applications include pain management, where music therapies use undulating, low-frequency soundscapes to induce relaxation and distract from chronic discomfort. A 2021 meta-analysis of music interventions confirmed reductions in perceived pain intensity and associated anxiety, with nature-inspired audio enhancing efficacy in some protocols.^[64] Post-2020 developments integrate music with virtual reality (VR) for geriatric care, including dementia, creating immersive environments to evoke memories and reduce agitation. Pilot studies from 2022-2025 report improved mood and engagement in participants, with music-based VR sessions leading to significant positive emotional shifts. As of 2025, VR music therapies for dementia show promise in reducing agitation through nature-inspired sessions.^[65]^[66] Despite these benefits, biomusic therapies face limitations in accessibility due to the high cost of biosignal equipment and specialized software, restricting use to well-resourced clinical settings. Additionally, effective implementation requires personalized calibration to individual signal profiles and musical preferences, as generic mappings may reduce engagement or efficacy.^[67]^[68]

Artistic and Educational Examples

One prominent artistic example of biomusic is the PlantWave installation, developed in the 2010s, which translates the bioelectric signals from plants into synthesized music, allowing audiences to experience vegetation as sonic performers in real-time installations and exhibitions.^[57] Similarly, composer Holly Herndon's 2019 album PROTO incorporates AI systems trained on her vocal biometrics to generate choral-like performances, blending human physiology with machine learning in live and recorded art pieces that explore collective identity through sound.^[69] In educational contexts, the UBEATS project, active in the 2010s, integrated biomusic into K-12 science curricula by using soundscape analysis of natural environments to teach ecology and biodiversity, enabling students to compose with recorded biophonies as a tool for understanding ecosystems.^[70] Workshops on composing with bird calls further exemplify this approach, where participants analyze avian vocalizations—such as those of songbirds—and adapt them into musical structures to foster appreciation for acoustic niches in nature.^[71] Notable cases in popular culture include Björk's 2011 Biophilia app, which features gamified interactions simulating natural processes like crystallization and pendular motion to engage users in creating music tied to biological rhythms.^[72] Analyses of historical works like those by The Beatles highlight the use of animal sounds in compositions such as "Good Morning Good Morning." These examples demonstrate biomusic's impacts in fostering interdisciplinary learning by bridging arts, sciences, and environmental awareness, as seen in curriculum models that enhance student engagement through sonic exploration.^[73] Public engagement events, such as Bernie Krause's soundscape concerts in The Great Animal Orchestra exhibitions, immerse audiences in biophonic recordings to highlight habitat acoustics and promote conservation.^[74] Looking to future trends in the 2020s, collaborative AI-human music has emerged in festivals, exemplified by the 2024 R² event where performers integrated real-time AI processing with live instrumentation to create hybrid soundscapes.^[75]
