Minor 13th chords

The Minor 13th (m13) chord is in theory a seven-note chord, but is played with one or more notes omitted on the guitar. The sound character of the 13th minor is a little dissonant – the 13th note is outside the relevant minor scale – and therefore it's not always a fitting substitute for minor 7th and minor 9th. Instead it's functionally is closer to that of a dim and aug chords, often used as an in-between chords.

There are different many different versions of this chord possible on guitar, but it's common to exclude one or more of the following: the fifth, the seventh, ninth and eleventh.
