A maj13 Guitar Chord | Play, Hear and Practice Interactively
An Amaj13 chord, also called A major thirteenth, is made of A, C#, E, G#, B, D and F#. The natural eleventh sits a half step above the major third and clashes with it, so it is often left out and the chord is still called maj13.
Two voicings are mapped out here, one of them with open strings. Spelled in thirds, the chord uses every note of the A major scale, so the two share the same seven pitches. To find each of these notes from any root, see intervals on the fretboard.
Use the interactive fretboard above to hear the chord as a strum and as an arpeggio.
A major 13th guitar chord is also written as Amaj13, AM13, AΔ13 or Ama13.
