Tips for playing A7♯9 on ukulele
On ukulele it takes a single finger (0004), which makes A7♯9 one of the simplest chords on the instrument. It leaves out the root, which a bass player (or your ear) fills in.
Notice the B♯ in A7♯9 (A C♯ E G B♯): each note of the chord takes its own letter (A–C–E–G–B), so the augmented 9th has to be written B♯ rather than C — the same key on a piano, spelled to fit the chord.
