Im having a very hard time resolving inthe last two bars of this song. I can walk the rest of it just fine, but the switch in the last 4 bars ( l E-7 l A7 l Bbmaj7 l E-7 A7 l ) has me thoroughly perplexed. It feels like it should end on a D maj7. Ive been walking this piece by staying in the key of D for the first 4 bars, C for the next four bars, and Bb for next four bars. But, the last 4 bars has dumbfounded me. Anybody have any experience with this piece.
