E Dominant b5, written E7b5, is built from E, G#, Bb and D: the root, major 3rd, flat 5th and minor 7th.
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 E7b5 as its tritone substitute.
