How to play C♯m7♭5 on ukulele

Shape 1, 0-1-0-2, reading from the G string on the left:

1. C♯: index finger, 1st fret of the C string.
2. B: middle finger, 2nd fret of the A string.
3. Leave the G and E strings open: G and E.

• Arch your fingers so their tips come down vertically. That keeps them off the open strings, which have to ring for the chord to sound complete.
• On ukulele you strum all four strings. The top G string is tuned higher than the C, which is why ukulele chords sound bright and close.

• 6-7-7-7: movable shape at the 6th fret, medium. A different set of strings gives a different color of the same chord.
