Q: what is tempo crisis when writing?
A: it's when you are working on a song and you are running through the part you have but you start running through it faster cuz you already know it, etc, and as a result you may end up writing the next section to fit better with a faster tempo (i.e. it would sound slow and empty if you actually kept it the same tempo that would have worked for the first half). it's any time you are writing a song and different parts seem to not work at each other's tempo
