- D Dominant 7
D Dominant b13, written D7b13, is built from D, F#, A, C and Bb: the root, major 3rd, 5th, minor 7th and flat 13th.
Its 3rd and 7th, F# and C, are its guide tones: they say what kind of chord it is, so voicings are built around them and the root is often left to the bass. Ab7, a tritone away, has the same two notes the other way up, so it can stand in for D7b13 as its tritone substitute.
