- Eb Dominant 7
Eb Dominant 9, written Eb9, is built from Eb, G, Bb, Db and F: the root, major 3rd, 5th, minor 7th and 9th.
Its 3rd and 7th, G and Db, 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. A7, a tritone away, has the same two notes the other way up, so it can stand in for Eb9 as its tritone substitute.
