B Dominant #11, written B7#11, is built from B, D#, F#, A and E#: the root, major 3rd, 5th, minor 7th and sharp 11th.
Its 3rd and 7th, D# and A, 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. F7, a tritone away, has the same two notes the other way up, so it can stand in for B7#11 as its tritone substitute.
