Understand and Play the A#6 Guitar Chord with Interactive Tools
Here for A sixth rather than A#6? The A6 page covers it.
Four notes make up the A# major sixth chord, A#6: A#, C##, E# and F##. It is a major triad with the sixth above the root added, and here that sixth is F##.
This page has three voicings, and every one needs a barre. All four chord tones fit inside the A# major pentatonic scale, a five-note scale that suits solos. A#6 sounds identical to Bb6, spelled Bb, D, F and G, and the double sharps in the A# spelling are why Bb6 is the name you will normally see.
Press play on the fretboard player at the top to hear A#6 strummed and as an arpeggio.
A# major 6th guitar chord is also written as A#6, A#maj6, A#M6 or A#add6.
