3Indications: what it is used for

Used as a tonic minor chord in jazz, gypsy jazz, bossa nova, tango and film music, often instead of a minor seventh. It is the i chord built from the melodic minor or Dorian scale, and the iv chord in a minor key (where it is a common pre-dominant). The minor sixth chord shares its notes with the half-diminished chord built on its sixth, which gives interesting reharmonisation possibilities. It also appears in cadences such as iv6–I in major keys (a borrowed minor four).

4Dosage: how to practise it

On guitar, learn the four-string shape rooted on the fifth string and the gypsy-jazz shape with the sixth on top; play them with a light swing at 120–180 BPM. On piano, play root-♭3-5-6 in all inversions and practise the minor line cliché (i–imMaj7–im7–im6). Practise iv6–I endings in major keys. On bass, arpeggiate 1-♭3-5-6. Ten minutes daily, alternating with m7 and mMaj7 to hear the colours. On guitar, also try the tonic m6 as a final chord at the end of a minor tune.

5Warnings and common mistakes

The sixth is major, not minor: m6 is not 'minor with a flat sixth'. Do not confuse it with m7♭5: same notes, different root, so the bass decides the name. In minor keys built on natural minor, the sixth degree is flat, so an m6 tonic implies melodic minor or Dorian. Avoid it if the melody contains the flat sixth. Some charts write 'm6' meaning m6/9; check the melody.
