A♯ minor 9th chord

Playing it

There’s no open-string way to play A♯m9 on guitar with the root in the bass, so the standard shape is a barre across the 6th fret (686668).

On piano, A♯m9 has three black keys (A♯, C♯ and G♯) and two white keys. In root position it spans more than an octave, so many pianists play the root with the left hand and the rest with the right.

On ukulele the usual A♯m9 shape is 3044, using three fingers.

Move a single note and A♯m9 becomes a different chord: drop the B♯ for A♯m7 and raise C♯ to C𝄪 for A♯9.

Where you’ll hear it

Notice the E♯ in A♯m9 (A♯ C♯ E♯ G♯ B♯): each note of the chord takes its own letter (A–C–E–G–B), so the perfect 5th has to be written E♯ rather than F — the same key on a piano, spelled to fit the chord.
