I have an idea for a song I'm working on but I'm unsure how to go about it or even if it's a good idea. The song is four verses long, no chorus, 3/4 time in C with a pretty straightforward I-IV-V progression. Each verse resolves with the root.
I was thinking about doing a key change, perhaps up a step to D, for the third verse for emphasis then back to C for verse four. Do you think this would be a good idea and, if so, how would I transition from C to D then back smoothly?
As a beginner I appreciate the help.
