A whole note, known as a semibreve in British English, is a basic symbol in Western musical notation representing a duration equivalent to four quarter-note beats in common (4/4) time, depicted as an open, oval-shaped notehead without a stem.[1][2] It functions as the longest standard note value in most modern music, filling an entire measure in 4/4 time and providing a foundational unit for rhythmic subdivision.[3][1]In relation to other note values, a whole note equals two half notes (each worth two beats) or four quarter notes (each worth one beat), allowing composers to build rhythmic structures by combining or dividing it.[3][4] Its duration remains relative to the tempo and time signature; for instance, in 3/4 time, a whole note exceeds the measure's three beats and thus cannot fit alone, requiring adjustments with shorter notes.[1] The corresponding whole rest, symbolized by a filled-in rectangle hanging from the fourth line of the staff, denotes silence for the same length of time.[1]When notated on a musical staff, the whole note's position determines its pitch, with the open notehead placed on or between lines according to the scale degree, and no stem or flag is added regardless of its placement above or below the staff.[1] Dotted whole notes, marked with a dot to the right of the notehead, extend the duration by half (to six beats), though this variant is less common in strict 4/4 contexts.[3] Overall, the whole note exemplifies the proportional rhythm system derived from medieval mensural notation, emphasizing clarity in sustaining tones or rests across genres from classical to contemporary music.[5]
Appearance and Notation
Visual Characteristics
The whole note is depicted as a hollow, oval-shaped notehead without a stem or flag, setting it apart from shorter-duration notes such as the half note, which features a similar but narrower open notehead with a vertical stem attached to the right side.[6] The notehead's form is an ellipse rather than a perfect circle, with a standard width-to-height ratio of approximately 1.96, where the width spans about the distance of two staff spaces and the height aligns with one staff space; this shape is slightly skewed, with the left edge tilted upward and the right edge downward for optical balance on the staff.[7] The enclosed white space (counter) within the oval is also elliptical, narrower and angled at about 35 degrees counterclockwise from vertical, ensuring the symbol's clarity in reproduction.[7]In standard placement, the whole note's head is positioned on the lines or in the spaces of the five-line musical staff to denote pitch, filling half the adjacent spaces when on a line or touching the lines above and below when in a space.[6] For pitches extending beyond the staff's range, short horizontal ledger lines are added, each representing an additional line or space, with the notehead centered on or between them to maintain proportional alignment.[8]Printed notation adheres to precise engraving standards for uniformity, as outlined in Elaine Gould's Behind Bars, where the whole notehead is rendered as a wider oval than that of the half note to enhance visual distinction and readability, with dimensions scaled to the staff height (typically 7mm for orchestral scores) and line thickness typically 1/10 to 1/8 of the staff space (around 0.15-0.2 mm).[9][10] Handwritten versions may exhibit slight irregularities in oval elongation or thickness due to manual execution, but best practices recommend approximating the printed proportions—horizontally elongated rather than circular—to avoid misinterpretation as other symbols.[11] The absence of beams or stems in this design emphasizes its role as a sustained, full-measure tone, equivalent to four quarter notes in common time.[12]
Duration and Rhythmic Value
In music theory, the whole note holds a standard duration of four beats within a 4/4 time signature, where it occupies an entire measure and forms the basis for common time structures.[13][14] This value positions the whole note as the longest basic durational symbol in simple meter, providing a foundational unit for rhythmic organization.[15]Relative to other note values, a whole note equals two half notes, four quarter notes, or eight eighth notes, reflecting a binary subdivision system where each longer note divides evenly into two of the next shorter duration.[16][17] This hierarchical relationship ensures consistent rhythmic proportionality across compositions.[18]Mathematically, the whole note represents four quarter-note beats, aligning with the 4/4 time signature's structure of one whole note per measure, expressed as the fraction 4/4 equaling a single whole note.[13][19]The actual temporal length of a whole note in seconds varies with tempo and is calculated as 240 divided by the beats per minute (BPM), assuming the quarter note receives the beat; for instance, at 60 BPM, it lasts 4 seconds.[20] This adjustment scales the note's duration inversely with tempo speed, maintaining its relative four-beat value.[21]
Terminology
Names in English
In American English, the standard term for the note that endures for the full duration of a measure in 4/4 time is the "whole note," emphasizing its complete rhythmic value within a bar.[22] This nomenclature highlights its role as the foundational unit in common time signatures.[23]In British English, the equivalent is termed the "semibreve," derived from the Latin semi- (half) and brevis (brief or short), signifying that it represents half the length of the longer breve note in medieval mensural notation.[24] The semibreve's name thus preserves the proportional logic of earlier European systems, where note values were hierarchically subdivided.[25]The shift to "whole note" in the United States emerged during the late 18th and 19th centuries, driven by early music educators seeking a simplified, mathematical terminology to accelerate learning for psalm and hymn singing among Protestant communities, diverging from the traditional British terms for greater accessibility in education.[22]In pedagogical materials of the era, such as English editions of Carl Czerny's Practical Method for Beginners on the Pianoforte, Op. 599 (first published 1839), the term "semibreve" appears alongside related durations like "minim," reflecting the persistence of British-influenced conventions before full adoption of American fractional names in U.S. teaching practices.[26]
International and Alternative Terms
In French musical notation, the whole note is termed ronde, a name derived from the round, hollow shape of its note head, emphasizing its visual form over durational aspects.[27] This terminology aligns with historical French practices where note names often reflect morphology, as seen in treatises from the 14th century onward.[28]German notation employs ganze Note for the whole note, a direct calque that translates to "whole note" and underscores its full-measure duration in common time, equivalent to four quarter notes.[4] This term has influenced American English nomenclature, where "whole note" emerged as a loan translation in the 19th century.[29]In Italian, the equivalent is semibreve, meaning "half breve," a designation retained from medieval mensural notation systems where the breve served as a primary unit of time.[30] This nomenclature persists in modern Italianmusic theory, linking contemporary usage to Renaissance-era conventions documented in sources like Prosdocimo de' Beldomandi's treatises.[27]Non-Western notations adapt the concept variably; in Chinesestaff notation, which incorporates Western symbols, it is called quányīnfú (全音符), literally "whole sound symbol," reflecting its role in filling a complete measure.[31] Shape-note systems, prevalent in American sacred music traditions since the early 19th century, occasionally refer to the unfilled note head as a "round note" to distinguish it from shaped heads used for solfège syllables, though duration remains tied to standard rhythmic values.[27]In solfège-influenced systems across Latin America, particularly in Spanish-speaking regions, the term redonda is used, again highlighting the circular note head and aligning with Iberian musical heritage.[32] This usage appears in pedagogical materials from countries like Mexico and Argentina, where it denotes the note's four-beat length in 4/4 time.[27]
Historical Development
Origins in Early Notation
The precursor to the modern whole note, known as the semibreve, emerged in the 13th-century mensural notation system codified by Franco of Cologne in his treatise Ars cantus mensurabilis (c. 1260), where it denoted a long-held tone as one of the primary units of measured duration alongside the longa and brevis.[33] This innovation represented a pivotal advancement from the earlier modal rhythms of the Notre Dame school, establishing fixed proportional relationships that enabled precise rhythmic control in polyphonic compositions.[34]Central to Franco's proportional notation, the semibreve served as the base unit for subdivision, typically divided into either two minims (in imperfect prolatio) or three minims (in perfect prolatio), with minims further subdivided into semiminims to accommodate intricate rhythmic patterns such as binary or ternary groupings.[33] These subdivisions allowed composers to notate durations in exact ratios, facilitating the synchronization of multiple voices in early motets and organa, where the semibreve's value could be altered through mensuration signs like the circle (perfect tempus) or semicircle (imperfect tempus).[34]The semibreve's conceptual roots trace to Gregorian chant and early polyphony, where sustained pitches in neumatic notation—such as the punctum or virga—provided models for long-held tones, transitioning from the flexible, text-driven rhythms of monophonic chant to the structured mensural framework needed for polyphonic interplay around 1200.[33] In works like those of the Notre Dame polyphonists, these long notes evolved into mensural forms to support harmonic alignment, with the semibreve bridging the unmeasured flow of plainsong to the beat-based precision of emerging motets.[34]A key surviving example appears in the Robertsbridge Codex (c. 1360), an early keyboard manuscript that employs mensural notation with void (hollow) note forms, including semibreves, to indicate extended durations beyond a single beat, reflecting the visual distinction for longer-held values in 14th-century English and continental practices.[35]
Evolution to Modern Usage
In the 15th century, during the transition to white mensural notation around 1420–1450, the semibreve evolved toward its modern form as a hollow oval without a stem in staff notation, representing sustained durations in polyphonic compositions.[36] Over time, as smaller note values like the quaver and semiquaver were introduced, the relative duration of the semibreve—originally half a breve and longer than the minim—shifted to become the longest standard note value in modern common time signatures. Composers such as Johann Sebastian Bach employed this symbol consistently in their scores, such as in the Well-Tempered Clavier, where it denoted prolonged tones to support harmonicresolution and contrapuntal lines, contributing to the fixation of its form across European musical practice. This standardization was facilitated by the invention of music printing in the late 15th and early 16th centuries, with Ottaviano Petrucci's polyphonic prints from 1501 allowing for precise reproduction of note shapes and rhythmic values in published works.[37]In the 19th century, innovations in music printing, particularly lithography invented by Alois Senefelder around 1798, revolutionized the dissemination of scores and further entrenched the whole note's appearance.[38]Lithography enabled detailed, cost-effective reproduction of complex notations on stone plates, making printed music accessible to amateur musicians and educators, and thus popularizing the symbol in orchestral and piano scores by composers like Beethoven and Chopin.[39] This technology reduced variations in handwritten copies, promoting uniformity in the whole note's visual and durational role as a four-beat value in 4/4 time.[40]By the 20th century, the whole note adapted in jazz and popular music genres, often combined with fermatas to indicate extended sustains over chord changes or dramatic pauses, as seen in lead sheets and big band arrangements.[41] In these contexts, it served not only for rhythmic fullness but also for expressive holds during improvisational breaks or ensemble rests, enhancing the genre's syncopated and flexible phrasing.[42] Whole rests, mirroring the note's shape, were similarly used with fermatas for prolonged silences in ballads and standards.[41]Music education reforms in the 20th century reinforced the whole note's role in modern pedagogy, ensuring its intuitive grasp in diverse musical traditions.
Musical Application
Role in Common Time Signatures
In common time signatures such as 4/4, the whole note occupies an entire measure, equivalent to four quarter notes or beats, providing a foundational rhythmic unit for structural stability.[43][44] This duration allows it to serve effectively for harmonic sustains, where it holds a chord or tone across the full bar to emphasize tonal centers, or for melodic resolutions, concluding phrases with a sense of completion and repose.[43]A notable application appears in the first movement of Beethoven's Symphony No. 1 in C major (Adagio molto – Allegro con brio, in 4/4 time), where whole notes in the horns and trumpets in bars 261–263 create a sustained C pedal point over a C7 chord, reinforcing the cadence to F major and underscoring harmonic tension release.[45] Similarly, in bars 160–172 of the same movement, sustained whole notes in the horns and trumpets form a dominant E pedal during the development section in A minor, maintaining continuity amid shifting harmonies.[45]In 2/2 (cut time or alla breve), the whole note equates to two beats, as the half note receives one beat per measure, yet it still fills the complete bar while preserving its open oval notation.[44] This equivalence to two half notes supports similar functions as in 4/4, such as sustaining pedals or resolutions, but at a tempo often perceived as faster due to the halved beat unit.[44]The whole note's alignment with bar lines in these signatures ensures precise measure completion, with its duration terminating exactly at the subsequent bar line to delineate clear phrase boundaries and facilitate ensemble synchronization.[43][44]
Adaptations in Irregular Meters
In 3/4 time, where each measure contains three quarter-note beats, the whole note—equivalent to four quarter-note beats—cannot fit within a single measure and must be subdivided using ties to maintain its full duration. This is conventionally notated as a dotted half note (three beats) tied to a following quarter note (one beat), ensuring the note's value spans the boundary between measures without altering its rhythmic length.[46] Such notation preserves the whole note's integrity while adhering to the meter’s constraints, a practice rooted in standard mensural principles where note values remain absolute relative to the quarter note.[44]In more complex irregular meters like 5/4 or 7/8, the whole note similarly exceeds the measure's capacity, necessitating ties across barlines or, in some cases, augmentation dots to extend durations beyond standard values when a single sustained tone is intended. For instance, in 5/4 time (five quarter-note beats per measure), a whole note is often written as a whole note tied to a quarter note to encompass the full measure, avoiding the use of a non-standard five-beat note shape.[47] In 7/8 (seven eighth-note beats), multiple tied whole notes or a whole note augmented with dots may be employed to bridge irregular phrases, particularly when emphasizing sustained harmonies over shifting pulses. These adaptations highlight the flexibility of notation in accommodating the whole note's fixed four-beat value against varying metrical frameworks.[48]Twentieth-century compositions frequently exploit these techniques to create rhythmic tension in irregular meters. Notation conventions, as outlined in authoritative guides, recommend placing ties clearly across barlines without interruption, and fermatas on the final note of a tied chain to indicate prolongation beyond the strict metrical boundary, allowing performers interpretive freedom in irregular contexts.[49] This approach ensures legibility and rhythmic precision, distinguishing adaptations in odd meters from the whole note's simpler role in common time.
