Notes

In the 3rd position, the chord is written (x/12)-12-11-9-9-9, while the notes are written (x/E) - A - C# - E - G# - E. This simply takes into account the optional note, which is the number/letter after the forward slash (/). We also separate double digits with a hyphen so as not to create confusion, otherwise the chord above would be written (x/12)1211999, which is too confusing - which fret belongs to which string? etc.

You will find major 7 chords used often in jazz music and less in mainstream music, however when used cleverly, they can enhance a piece tremendously. The Amaj7 - 3rd position is a little difficult at first, but when you master it, what a sound!... if you can play it with the optional note, you are doing very well.

Standard keys using the A major 7 chord: A Major, E Major, F#m, and C#m. Each of the minor keys is the relative minor of the major keys, i.e., A/F#m, E/C#m. If you are playing songs in any of these keys, you may come across an Amaj7 chord.
