How to play A♯m(maj7)
About the A♯ minor-major 7th chord
Playing it
There’s no open-string way to play A♯m(maj7) on guitar with the root in the bass, so the standard shape is a barre across the 1st fret (x13221).
On piano, A♯m(maj7) has two black keys (A♯ and C♯) and two white keys.
On ukulele the usual A♯m(maj7) shape is 3110, using three fingers.
Related chords
Take away the root and the other three notes form C♯aug (C♯ E♯ G𝄪) — so you can think of A♯m(maj7) as C♯aug with A♯ added underneath.
Move a single note and A♯m(maj7) becomes a different chord: drop the G𝄪 for A♯m, raise C♯ to C𝄪 for A♯maj7, lower G𝄪 to G♯ for A♯m7 and swap G𝄪 for F𝄪 for A♯m6.
Where you’ll hear it
Notice the E♯ in A♯m(maj7) (A♯ C♯ E♯ G𝄪): each note of the chord takes its own letter (A–C–E–G), so the perfect 5th has to be written E♯ rather than F — the same key on a piano, spelled to fit the chord.
