B Lydian — 4-Voice Polysynth

The B Lydian lit key by key — roots pinned, degrees named, audio ready.

B Lydian carries 7 notes per octave (modes family), drawn here straight onto the 4-Voice Polysynth's keys with every root pinned — no tablature in between, the keyboard is the map.

Major with a raised 4th (#4) — dreamy, ethereal, and floating. Often called the brightest mode, with an otherworldly suspended quality.

Heard in: Film scores, progressive rock, jazz — Joe Satriani's "Flying in a Blue Dream", John Williams, Steve Vai.

The 4-Voice Polysynth answers touch, so practice these maps at more than one dynamic — the pattern is the same, but the hand that plays it soft and loud owns it twice.
