What makes B♯ Lydian Dominant different
Lydian dominant combines Lydian's raised fourth with Mixolydian's lowered seventh; against Mixolydian, the ♯4 is the only change. It's the fourth mode of melodic minor, also called the acoustic or Bartók scale, because its ♯4 and ♭7 sit close to the 11th and 7th harmonics of the root. Its tonic chord with the ♭7 is a dominant seventh, and the ♯4 on top of it makes the chord written 7♯11. That makes it the scale for dominant chords that don't resolve down a fifth, such as IV7, ♭VII7 and tritone substitutions. On B♯, B♯ Lydian Dominant has E𝄪 where B♯ Mixolydian has E♯; every other note is shared with B♯ Mixolydian (B♯ C𝄪 D𝄪 E♯ F𝄪 G𝄪 A♯).
