Bdim Ukulele Chord
A dark, unsettled diminished triad spelling B, D and F. Built from stacked minor thirds, it never sounds at rest, so it typically works as a passing chord pulling toward the next harmony, a familiar sound in jazz, classical and dramatic pop.
Also known as
- B°
- B °
- B dim
- Bdiminished
- B diminished
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
This is the movable diminished block played low at the first fret: pinky on the G string, middle on the C string, index on the E string and ring on the A string. Four fingers in a tight cluster down here feels cramped, so arch them on their tips, and remember the same shape becomes C dim, C# dim or D dim as you slide it up the neck.
