I haven't been playing for very long but lately I have been able to improvise quite a bit over songs, especially songs that have great solos like 'Stairway to Heaven' or 'November Rain.' But when I got to compose my own solos I realized that I only knew how to improvise when I knew what scales certain songs were in. For example, yesterday I was fooling around with: Bm (7th fret), A (5th fret) and Em. This is a ii-i-V right? Anyway... what scales or modes can I use to solo over this progression?
Thank y'alls for any advice.
