soloing over so many chord changes in a solo is incredibly difficult, as evident in jazz. so far im very weak jazz soloist and all i do is play blues over jazz, i get away with it somehow on many songs.

but what i need to know is what scales is should use to work with the jazz songs?, if someone could help me figure out how to possibly solo over chord changes every measure... from Dmin7 to e7b9 then maj9s... its crazy
