Well, I missed the deadline for the contest, so no prog-rock from me.
I had something started, but it seemed so contrived. I was placing meter changes and key shifts just to be adding them, which is not creative at all. In frustration, I gave up on it.
Mind you, I'm not giving up on prog-rock entirely as I love some prog, but it's just not working for me right now. I really need to get a better handle on shifting to and from different meters.
So I suppose this post is on-topic because it illustrates how I improperly wrote some "music".
TO Monomer and Maikeru:
One thing that helps me create original music is to start with something simple, a three chord progression for instance. This allows me to build upon this structure. Dismiss any notions of sounding like something else, or try to intentionally change a chord so that you don't sound like a song that is swimming in your head. Once you get past the hump, it will be a lot less intimidating.
Starting a new song is always my least favorite part.
