Wicked is the tale of Elfaba, the " Wicked witch of the west". It takes you from her introduction to the world to her "passing" a child conceived who is GREEN! It is the narrative of her life as she goes to class, meets GAlinda who later turns out to be simply Glinda, finds she has amazingly solid mystical forces, and how she comes to be viewed as an outcast rather than the solid, empathetic young lady she truly is.
I'm pretty sure it is B a minor interval, because a note is lowered, it is a minor. Sorry for the wait, had to do some digging in my memory. Good luck!
The answer is interval.
I do have some experience, I'm a pianist and singer.
