F Dominant 9, written F9, is built from F, A, C, Eb and G: the root, major 3rd, 5th, minor 7th and 9th.
Its 3rd and 7th, A and Eb, 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. B7, a tritone away, has the same two notes the other way up, so it can stand in for F9 as its tritone substitute.
