Also written CmMaj7, Cminmaj7 or Cmmaj7
C minor major 7th is built from C, E♭, G, and B. This advanced ukulele shape uses a full barre at the 3rd fret, so the index finger must hold three strings cleanly.
The same three notes, with a different one in the bass.
C minor major 7th stacks a minor 3rd, perfect 5th, and major 7th over C. The major 7th B is a leading tone that gives the chord its tense, unresolved quality. Compare it to C minor, which omits the B and sounds more settled.
C minor major 7th works as a dramatic substitution in C minor progressions, often resolving to C minor or C 5th. Its dark, tense sound suits jazz ballads and film-score passages. Try it before C minor for a brief harmonic lift.
The default Cminmaj7/E♭ inversion puts E♭ in the bass for a darker, more ambiguous sound. The open position with C in the bass at the 3rd fret is brighter and easier to finger. Choose the barre version for a fuller, more sustained tone.
C minor major 7th is played at the 3rd fret as 4 3 3 3: barre your index finger across fret 3 and pinky finger on the G string at fret 4.
Tip — The index barre must fret the C, E, and A strings cleanly at the 3rd fret while the pinky reaches the 4th fret on the G string.

C minor major 7th is written Cmmaj7, Cminmaj7, or CmM7. It is also called C minor sharp 7 or C minor ♯7.
C minor major 7th adds the major 7th B to the C minor triad. That B creates a leading tone that pulls toward C, giving the chord a more unsettled sound.
The tension comes from the major 7th B against the minor 3rd E♭. That interval is an augmented 5th, which creates a sharp, dissonant edge.
Yes, but it changes the color. C minor major 7th works when you want a more dramatic, unresolved sound, especially before resolving to C minor.
