- E Dominant 7
E Dominant #9, written E7#9, is built from E, G#, B, D and G: the root, major 3rd, 5th, minor 7th and sharp 9th.
Its 3rd and 7th, G# and D, 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. Bb7, a tritone away, has the same two notes the other way up, so it can stand in for E7#9 as its tritone substitute.
