Tips for playing A7♯9 on guitar
There’s no open-string way to play A7♯9 on guitar with the root in the bass, so the standard shape is a barre across the 5th fret (575658).
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.
