What CmM7 is built from
Counting up in semitones from C:
| Note | Interval | Semitones from root |
|---|---|---|
| C | root | 0 |
| E♭ | minor third | 3 |
| G | perfect fifth | 7 |
| B | major seventh | 11 |
Move all four of those the same distance and you get the same chord on another root — that is what the minor-major seventh formula 0 – 3 – 7 – 11 means.
How to play CmM7
Leave the low E string out. Lay your first finger flat across fret 3 and let the other fingers take the notes above it. The shape runs from fret 3 to fret 5.
All four strings are played. The G and C strings ring open. The shape runs from fret 6 to fret 7.
Play C, E♭, G and B together. That is three white keys and one black.
Numbers in the grids are frets. Where a number is printed beside a grid, that is the fret the top row stands for; otherwise the thick bar at the top is the nut. A circle above a string means play it open, a cross means leave it out.

CmM7 on the stave
The same four notes written on a treble stave, spelled the way a minor-major seventh is spelled — one letter for every other step, with whichever accidental reaches the pitch. That is why it reads C, E♭, G and B, and not the same sounds written some other way.
Which keys CmM7 belongs to
No major scale contains all four of these notes. It does sit inside the harmonic minor scale, which is where it is usually met:
- C harmonic minor, on degree i(♮7)
Other chords on C
Same root, different notes above it.
