Cm7♭5 Ukulele Chord
Dark and unsettled, Cm7♭5 stacks C, D#, F# and A# into a half-diminished sound that leans forward rather than resolving. It opens minor-key ii-V-i turnarounds in jazz and lends a brooding, sophisticated color to ballads and film cues.

How to Play This Chord
Position your fingers on the fretboard as shown in the diagram. The vertical lines represent the four strings, from the top G string (left) to the A string (right), and the horizontal lines are the frets. Numbers inside the dots indicate which finger to use: 1 (index), 2 (middle), 3 (ring), 4 (pinky). An X means don't play that string; an O means play it open. A bar spanning multiple strings means one finger presses across all of them at once — this is known as a barre chord.
Tips & Tricks
Place your index on the E string at fret 2, then stack middle on the G string, ring on the C string and pinky on the A string, all at fret 3. The three same-fret fingers can crowd each other — fan your knuckles slightly and press near the fret so the high re-entrant G string still rings clean.
