Explore A#5 Guitar Chord: Play, Learn, and Practice Interactively
The A#5 chord, or A# power chord, holds just two notes: A# and E#, a root and a perfect fifth with no third. E# is the same pitch as F, so charts normally write this chord as Bb5 (Bb and F), which sounds identical on the same frets.
One listed shape appears here, spread between frets 6 and 8, and the player at the top of the page can put the note names as labels on the fretboard, so you see where A# and E# land. Both notes sit inside the A# minor pentatonic scale, a dependable choice for riffs over this chord.
The A# power chord is also written as A#5, A#(no 3rd) or A#(omit 3).
