Hi guys, I wonder if you can help me.. my theory isn't great and I'm trying to write a blues tune that changes keys several times after a 12 bar (I-IV-V) verse, and then resolves back to the original key. Using the IV chord I have made the keys changes like this: Verse 1 = 12 bar in E Verse 2 = 12 bar in A Verse 3 = 12 bar in D Verse 4 = 12 bar in ? Verse X = 12 bar in ? Verse 5 = 12 bar in E Could anyone explain how do I get back (if I can) to the E again, without using A or the D again? Thanks!!
