What notes are in the B9 chord?
The B9 chord is built from five notes: B, Eb, Gb, A and Db (the root, major 3rd, perfect 5th, minor 7th and 9th). That flat seventh makes a dominant 7th restless. It leans forward and wants to resolve to the next chord, which is why it turns up all over blues and folk. New to these? Have a read about seventh chords.
