Other ways to play A♭add9

Playing A♭add9 with a capo

With a capo you can skip the harder shapes: capo on the 4th fret and play the open Eadd9 shape (0-2-4-1-0-0). Everything above the capo is fingered exactly like the open chord.

A♭add9 chord changes

These are the changes you'll meet most often with A♭add9, using the first shape of each chord.

A♭add9 is A♭ major with the ninth (the note a whole step above the root, an octave up) added. A♭add9 keeps the major sound and adds sparkle, which makes it a drop-in replacement for A♭ in quiet passages. The slow arpeggio button above makes that quality easy to hear.

Getting A♭add9 under your fingers

Before strumming, play 4-1-1-3-1-4 note by note: A♭ then B♭ then E♭ then B♭ then C then A♭. A dead note tells you exactly which finger to fix. Next, alternate 4-1-1-3-1-4 and x-11-10-8-11-x, slowly, until the change takes less than a beat.

You may also see it as G♯add9; nothing changes on the guitar.
