The major sixth (M6) is a consonant interval with a warm, lyrical color. It spans 9 semitones and appears often in melodies, chord extensions, and smooth voice leading.
Construction and spelling
M6 runs from a note to its sixth letter name, such as C to A, F to D, or D to B. It belongs to the major/minor interval family. Correct spelling keeps harmonic function and tonal context clear.
Harmonic and melodic usage
Melodically, M6 leaps sound expressive and singing-friendly, common in lyrical themes. Harmonically, sixth relationships appear in first inversion sonorities and in 6-chord colors. In arranging, M6 contributes warmth without strong dissonant pull.
Examples
- Melodic lines with characteristic sixth leaps in songs and themes
- Major 6 chord color in jazz, pop, and soul voicings
- Voice-leading patterns linking chord tones by sixth
In practice
Practice M6 ascending and descending from many roots and sing it against drones to lock intonation. Compare M6 with m6 to hear brightness versus darker color. Reliable M6 recognition improves melodic phrasing and harmonic awareness.
