Abmaj9 stands for the Ab major ninth chord, built from Ab, C, Eb, G and Bb. The top four notes, C, Eb, G and Bb, spell a C minor seventh chord, so maj9 is a major triad over a minor seventh built on its third.
The Ab major scale holds each of these notes, so it shows you which neighbouring notes fit. The page lists three voicings of Abmaj9, two of them barre shapes. If you want to know why these notes stack up this way, see how chords are built.
Strum the chord in front of your microphone and the player at the top shows which strings sound and which are muted.
Ab major 9th guitar chord is also written as Abmaj9, AbM9, AbΔ9 or Abma9.
