Want a structured chord roadmap instead of jumping between pages?
Go to the full guitar chords tutorial.
The A#sus4 chord, or A# suspended fourth, holds A#, D# and E#: a root, a perfect fourth and a perfect fifth. Since E# is just the note F, charts tend to favour the Bbsus4 spelling (Bb, Eb and F) for the same sound.
Three shapes are listed on this page, all of them barre chords, between frets 1 and 8. Switch on the labels in the chord player at the top and every note carries its name, so you can check the A#, D# and E# as you finger them. The A# Mixolydian scale contains all three chord notes.
A# suspended 4th guitar chord is also written as A#sus4, A#sus or A#4.
