Want a structured chord roadmap instead of jumping between pages?
Go to the full guitar chords tutorial.
A double sharp is needed to spell the A# major chord: A#, C## and E#. It sounds identical to Bb major, which uses the friendlier notes Bb, D and F, so you will mostly meet it under that name.
This page lists three voicings, all of them barre shapes. The major third above A# is C## rather than D, which is why Bb is the usual spelling. The A# major scale contains all three notes.
Hear the chord strummed and as an arpeggio in the fretboard player at the top.
A# major guitar chord is also written as A#, A#maj, A#M or A#Δ.
