i am currently writing a song, and I need to pass between a very sad sounding 4/4 time signature, to a 12/8 time signature, which is a more happy sounding time signature. I am not willing to change either part. is there any sort of transition move that i can play between them to make a passage between them more natural?
Not sure why this question has so many down-votes.
Easy, just make your quarter note equal to the new dotted quarter so the pulse remains equal.
