ok now I understand why using a blues scale with a major chord progression sounds wrong.I really appreciate your help- great answer to my question even though it will take some time to fully comprehend it all.I made a drawing of a neck and put down all the note locations of an E major scale throughout all 12 frets on all 6 strings.Thats when I noticed that the E blues scale contained different note locations that just seemed out of key.Thanks for telling me it's a minor key.These scale patterns are very difficult but i guess my brain will catch on eventually. Practice, practice, practice.
