Changing chords from A

A sounds five strings with one string muted: three fretted positions all at fret 2, plus two open strings. The quickest changes leave fretted notes where they are, so the hand pivots instead of lifting off the neck. These are the chords in this library that share the most fretted notes with the A shape.

  • A to A7: keep two fretted notes in place (4th string fret 2, 2nd string fret 2), no new positions to fret.
