Harmonic field of Ab major on electric guitar

Ab major: Ab – Bb – C – Db – Eb – F – G. In the shapes below, the tonic opens with the bass on Ab. On the electric guitar a chord needs only a few clear notes — the amp sustains them and fills the space, so you mute the strings you are not playing and let the tone carry the rest. Plugged into an amp, each chord sustains for as long as you hold it, and the tone — clean or driven — shapes the whole sound.
