Minor 7th chords

The minor 7th chord (abbreviated m7 in chord names) is a four-note chord, but due to the characteristics of the guitar, the chords can involve four to six notes (in some cases with duplicated notes). The minor 7th is similar to the dominant 7th, but is distinguished by its minor third.

The chord is built by a root, a minor third, a fifth and a minor seventh. Below you can see m7 chords in mostly open position presented and by scrolling down further you can also see minor seventh barre chords.

To look closer at this certain chord type we can take Am7 as an example. Am7 consists of four notes: A, C, E and G. Played as an open chord on the guitar it includes the following notes (from 5th to 1st string): A, E, G, C and E. The E note is duplicated, not because it's the most important note, but due to the circumstance of the instrument and how it's tuned.

Sometimes, a note is omitted and transformed the minor 7th to a three-note chords. In these cases, the fifth is normally left out.
