The minor sixth (m6) is a consonant interval with a dark, nostalgic color. It spans 8 semitones and appears in melodic writing, minor harmony, and expressive voice-leading.
Construction and spelling
m6 runs from a note to its sixth letter name, such as C to A♭, E to C, or A to F. It belongs to the major/minor interval family. Clear spelling helps distinguish m6 from enharmonic alternatives and keeps harmonic function readable.
Harmonic and melodic usage
Melodically, m6 leaps often sound dramatic and emotional. Harmonically, m6 relationships show up in minor colors, inversions, and line writing between chord tones. In arranging, it adds depth without the sharp friction of a minor second.
Examples
- Lyrical melodies featuring descending or ascending minor sixth leaps
- Minor-key chord and bass movement highlighting m6 color
- Voice-leading links between upper notes and bass tones
In practice
Practice m6 from several roots in both directions and sing it over drones to lock intonation and color. Compare m6 with M6 to hear the darker versus brighter quality. Reliable m6 recognition improves expressive phrasing and harmonic listening.
