Why it sounds like that

A major is built from the formula 1, 3, 5, with the major third C♯ giving it its bright quality. Compare it to A minor, which lowers the third to C.

What goes wrong with A major?

  • Letting the low E string sound through and muddy the bass.
  • Pressing the barre too flat and deadening the high e string.

When to use it

A major is the tonic in A major, so it anchors progressions like A–D–E, the I–IV–V. It also appears in D major and E major keys. Use it for strummed rock, country, and pop.

Changing to and from A major

  • From A major to D major, lift the barre and move your fingers to the D shape, keeping the index on the G string.
  • Sliding the shape down two frets to the 3rd fret gives G major.

Which voicing to use

The open position is the easiest and most common, with A in the bass. The 5th fret barre shape gives the same voicing higher up. For a different bass, use the A/C♯ inversion to put C♯ in the bass.

Common questions

How is A major written?

A major is written as A, Amaj, or AM. There is no alternate root spelling for A major.

What is the difference between A major and A minor?

A major has a major third (C♯), while A minor has a minor third (C). This changes the chord from bright to somber.

Why is the low E string muted in the open A major shape?

The low E is a chord tone, but it is muted to preserve the A bass note and keep the voicing clear.
