Why it sounds like that

A major 11th is built from the formula 1, 3, 5, 7, 9, 11 over A. The 11th, D, adds a suspended color above the major 7th. Compare it with A major 9th, which stops at the 9th.

What goes wrong with A major 11th?

  • Let the high e string buzz under the barre.
  • Allow the pinky to flatten onto the B string.
  • Mute the D string with the middle finger's underside.

When to use it

A major 11th works as the tonic in A major, especially in the I–IV–V–I progression A–D–E–A. It suits jazz, neo-soul, and slow ballads where the added 11th softens the major 7th. Try it in place of A major for a lush ending.

Changing to and from A major 11th

  • Sliding the shape down two frets to the 3rd fret gives G major 11th.
  • From A major, lift the pinky and move the middle and ring fingers down one string each.

Which voicing to use

The 5th-fret voicing keeps A in the bass for a grounded root position. The C♯ inversions put the third in the bass, making the chord sound brighter and less stable.

Common questions

How is A major 11th written?

A major 11th is written as AM11 or Amaj11. The root is A, and it has no enharmonic alias.

What is the difference between A major 11th and A major 9th?

A major 11th adds the 11th, D, to the five notes of A major 9th. The 11th creates a suspended sound against the major third.

Why does the 5th-fret shape use a barre?

The barre at fret 5 covers the root A on string 5, the fifth E on string 6, and the ninth B on string 2. It frees the other fingers for the 11th and major 7th.
