I am wondering if someone could explain the makeup of this run of notes. It is from Canzone by Barber for flute, and occurs in the fourth to last measure. The piece has a key signature of E Major. Here is the run: F♮, G#, B♮, C#, E♮, G♮, A#, E#, A♮, B#, E
I'm pretty sure it's a combination of different scales, but I can't really figure out how to describe it. There's no normal scale with F♮ & G#, or G♮ & A#, let alone all 4.
Are there any particular terms that could be used to describe the pitch collection used in this passage? Is there a particular combination of known, named scales that comprise this passage?
