How A works

A major has a black key in the middle again, and it is a chord guitarists call for constantly. A–C♯–E is also the upper half of several dominant chords, so the shape pays for itself as soon as you reach the sevenths.

A inversions

An inversion keeps the same notes and changes which one is at the bottom. That matters because it lets you move between chords without jumping: the closer the notes of the next chord are to the ones your hand is already holding, the smoother it sounds and the easier it is to play. Root position first, then two inversions.

  • Root position

    A–C♯–E — the root, A, is at the bottom.

  • 1st inversion — C♯ in the bass

    C♯–E–A — the same three notes, reordered so C♯ is lowest.

  • 2nd inversion — E in the bass

    E–A–C♯ — the same three notes, reordered so E is lowest.

Common mistakes on A

  • Playing C natural, which produces A minor.
  • Lifting the whole hand to reach C♯ instead of just moving the finger.
  • Rolling the notes so they arrive one at a time; a triad should sound as a single event.
