Eb major 13th chord
Ebmaj13 chord for piano with keyboard diagram.
Explanation: The E flat major thirteenth is a six-note chord (the 11th, Ab in the case of Dbmaj13, is normally excluded). For practical reasons the chord is normally played with omitted notes and/or inverted. It is often abbreviated as Ebmaj13 (not to be confused with Eb13).
Theory: The Eb major thirteenth chord is constructed by extending the major eleventh chord with a major thirteenth note.
Notes: Eb - G - Bb - D - F - C
