I never really understood how to solo over chord progressions. I've been playing for a while and tend to avoid soloing because I never really felt comfortable doing it (and honestly I'm much more comfortable laying down a groove than soloing). I think a good solo does both, lays down a good groove and shows off technique but I always have trouble connecting phrases through chord progressions. One chord jams are fine but throw in three or four chords (or more) and I tend to over think it. Any help or exercises that can help with this? Thanks!
