E minor
E minor is a minor scale and the key based on the note E, consisting of the pitches E, F♯, G, A, B, C, and D in its natural form.[1] Its key signature features one sharp, F♯.[2] E minor is the relative minor of G major, sharing the same key signature, as the tonic of the relative major is a minor third above that of the minor key.[2] The scale follows the Aeolian mode pattern of whole and half steps: whole, half, whole, whole, half, whole, whole.[3] Like other minor keys, E minor has three principal forms: natural, harmonic, and melodic. The harmonic minor raises the seventh scale degree to D♯, creating a leading tone for stronger resolution in cadences.[1] The melodic minor raises both the sixth (to C♯) and seventh (to D♯) degrees when ascending, reverting to natural minor when descending, to provide smoother melodic motion.[1] The primary diatonic chords in E minor are i (E minor), ii° (F♯ diminished), III (G major), iv (A minor), v (B minor), VI (C major), and VII (D major), with frequent use of the harmonic minor's V (B major) for dominant function.[3] E minor is prominent in classical music, evoking a somber yet expressive mood in numerous works. Notable compositions include Pyotr Ilyich Tchaikovsky's Symphony No. 5, Johannes Brahms's Symphony No. 4, Felix Mendelssohn's Violin Concerto, and Frédéric Chopin's Prelude in E minor, Op. 28, No. 4.[4][5][6]Scale and characteristics
Natural minor scale
The E natural minor scale consists of the pitches E, F♯, G, A, B, C, D, and E, both ascending and descending, without any alterations to these notes.[1] This sequence forms the diatonic foundation of the key, encompassing one octave from the tonic E to the upper E.[7] The interval structure follows the pattern of whole step, half step, whole step, whole step, half step, whole step, whole step (W-H-W-W-H-W-W), which defines the natural minor scale universally, starting from the tonic.[7] In the E natural minor scale, this manifests as a major second (E to F♯), minor second (F♯ to G), major second (G to A), major second (A to B), minor second (B to C), major second (C to D), and major second (D to E).[8] The scale degrees are named as follows: tonic (1st degree: E), supertonic (2nd: F♯), mediant (3rd: G), subdominant (4th: A), dominant (5th: B), submediant (6th: C), and subtonic (7th: D).[9] These designations provide the structural framework for tonal relationships within the scale.[10] The relative major of E natural minor is G major, which shares the same key signature of one sharp (F♯) and begins on the sixth degree of the E minor scale.[11] This relationship allows the two keys to use identical pitches, facilitating modal interchange in composition.[12] Acoustically, the defining feature is the minor third interval from the tonic E to the mediant G (spanning three semitones), which produces a narrower sonic width compared to the major third, contributing to the scale's characteristic minor tonality often associated with melancholy or introspection in musical expression.[13] This interval's consonance, while imperfect, supports stable harmonic foundations while evoking emotional depth.[14]Harmonic and melodic variants
The harmonic minor scale is derived from the natural minor scale by raising the seventh degree by a semitone, creating a leading tone that strengthens the resolution to the tonic, particularly in dominant-to-tonic progressions such as V-i.[15] In the key of E minor, the pitches of the harmonic minor scale are E, F♯, G, A, B, C, D♯, E.[7] This alteration enhances the dominant function by allowing for a major triad on the fifth scale degree and a fully diminished seventh chord on the leading tone, providing greater harmonic pull toward the tonic.[15] The melodic minor scale modifies the natural minor scale differently, raising both the sixth and seventh degrees by a semitone when ascending to facilitate smoother melodic lines and avoid the awkward augmented second interval present between those degrees in the harmonic minor.[15] For E minor, the ascending melodic minor scale consists of the pitches E, F♯, G, A, B, C♯, D♯, E, while the descending form reverts to the natural minor pitches: E, D, C, B, A, G, F♯, E.[7] This bidirectional adjustment ensures melodic fluency in ascent without compromising the established minor tonality in descent, primarily serving melodic rather than strictly harmonic purposes.[16] In terms of interval structure, the harmonic minor scale follows the pattern whole step, half step, whole step, whole step, half step, augmented second (W+H), half step, distinguishing it from the natural minor's even distribution and introducing tension via the augmented second between the sixth and seventh degrees.[15] The ascending melodic minor, by contrast, employs a more uniform pattern of whole step, half step, whole step, whole step, whole step, whole step, half step, which parallels the major scale's intervals more closely for melodic ease while maintaining the minor third from the tonic.[7] These variants thus address specific limitations of the natural minor scale in harmonic resolution and melodic contour, respectively.[15]Key signature and notation
Sharps, flats, and clefs
The key signature of E minor features a single sharp, F♯, positioned on the top line of the treble clef staff and on the fourth line from the bottom of the bass clef staff. This signature indicates the pitches E, F♯, G, A, B, C, and D for the natural minor scale, without any flats in the primary notation.[17][1] While the core key signature contains no flats, composers often introduce occasional accidentals—such as sharps or flats on other degrees—to incorporate modal mixture or chromatic elements, altering the scale temporarily for expressive purposes. In treble clef notation, the tonic E typically appears on the first ledger line below the staff, emphasizing its role as the foundational pitch; in bass clef, the tonic E (in the octave around middle C) is notated in the third space of the staff, facilitating readability across octaves.[18][1] E minor serves as the relative minor of G major, sharing the identical one-sharp key signature, which simplifies transposition between these tonalities. This key is particularly prevalent in violin and guitar music owing to the alignment with open string tunings—violin strings (G, D, A, E) and guitar open strings (E, A, D, G, B, E) incorporate several notes from the E minor scale, enabling resonant, open-position playing without excessive fingering.[19][20] Historically, notation for what would become E minor in early music relied on modal signatures derived from Gregorian chant traditions, often lacking fixed accidentals and emphasizing mode over tonality; by the post-Baroque era, modern tonal key signatures standardized the single F♯ to delineate the minor key clearly. E minor holds the position adjacent to G major in the circle of fifths, reflecting its single-sharp structure.[21][22]Position in the circle of fifths
In the circle of fifths, E minor occupies the position as the relative minor to G major, located two steps clockwise from C major at the top of the diagram, reflecting its key signature of one sharp (F♯).[23] This placement situates E minor within the sequence of minor keys that follow their relative majors in a clockwise progression, emphasizing relationships built on perfect fifths.[24] The parallel major of E minor is E major, which features four sharps (F♯, C♯, G♯, D♯) and is positioned four steps clockwise from C major.[25] Its dominant key is B major, with five sharps (F♯, C♯, G♯, D♯, A♯), located one step clockwise from E minor, while the subdominant is A minor, which has no sharps or flats and lies one step counterclockwise.[26] These adjacent positions highlight E minor's close tonal connections, sharing multiple scale degrees with neighboring keys to facilitate smooth modulations in Western music.[26] Modulation from E minor is particularly straightforward to its relative major G major, utilizing the identical key signature, or to the dominant major B major via the shared leading tone and common tones.[26] Pivot chords, such as the subdominant A minor (i.e., iv in E minor), often serve as bridges to these related keys, enabling fluid shifts without abrupt changes in tonality.[26] E minor's location in the circle also underscores its prevalence as a tonal center in Western compositions, especially for string instruments like the violin and guitar, where the tonic E aligns with open strings for natural resonance and ease of execution.[27][28]Diatonic harmony
Scale degree chords
In the E minor key, diatonic chords are triads constructed by stacking thirds using only the notes of the natural minor scale (E, F♯, G, A, B, C, D). These seven chords form the harmonic foundation of the key, each built on a successive scale degree and exhibiting specific qualities and functional roles in tonal music.[29][30] The tonic chord (I) is E minor, comprising the notes E-G-B; it serves as the tonal center, providing resolution and stability.[30][29] The supertonic chord (ii°) is F♯ diminished (F♯-A-C), a tense, unstable sonority that often functions as a pre-dominant, leading strongly toward the dominant chord.[30][31] The mediant chord (III) is G major (G-B-D), introducing a brighter, relative major quality that can temporarily shift the mood toward optimism while remaining diatonic.[30][29] The subdominant chord (iv) is A minor (A-C-E), evoking a melancholic, introspective character as it pulls away from the tonic without the full tension of the dominant.[30][29] The dominant chord (V) in the natural minor is B minor (B-D-F♯), a minor triad that provides a softer resolution compared to major dominants; however, in harmonic minor contexts, it is often altered to B major (B-D♯-F♯) for stronger leading-tone tension.[30][31] The submediant chord (VI) is C major (C-E-G), functioning as a mediant in the relative major (G major) and often used for deceptive cadences that avoid direct tonic resolution.[30][29] The subtonic chord (VII) is D major (D-F♯-A), offering a major quality that can substitute for the dominant in certain contexts, though it lacks the leading-tone pull; in harmonic minor, the leading-tone chord (vii°) becomes D♯ diminished (D♯-F♯-A) for heightened tension.[30][31] Overall, the diatonic triads in E natural minor consist of three minor chords (i, iv, v), three major chords (III, VI, VII), and one diminished chord (ii°), creating a palette dominated by minor tonality with opportunities for modal mixture.[29][30]| Scale Degree | Roman Numeral | Chord | Notes | Quality | Primary Function |
