C#m6 shares all four notes with A#m7b5. Same keys, different bass: from C# it is a minor sixth, from A# a half-diminished seventh.
When to play C#m6
- C#m6 works as a home chord in C# minor, a colour heard in film and jazz endings.
- Inside B major the same four notes are the ii chord, so it fits there with no outside note.
Make C#m6 automatic
- Find C#, then add the other notes one at a time: C#, E, G# and A#.
- Play C#m, then C#m6, then C#m again, and hear what the 6th does to the minor colour.
- Alternate root position and 1st inversion, keeping shared notes still.
- Then test it in random order among other chords: recall under time pressure is what sticks.
Five minutes a day is enough to make C#m6 feel easy.
