I've read up on all of my old forum posts, and I can not tell you all how grateful I am to have had your support and feedback in the past
Thanks everyone! Keep on composing :D

I have felt for a long time that the point of analysis is recognizing common patterns, so that you can compare and see similarities between different uses of these patterns, be able to discuss them, helps you remember them and also gives you something to substitute with if you need to.
Also it allows you to recognize unusual patterns, since you know the common ones.
I don't think it's ultimately very helpful to composition, though. It's helpful for thinking about chord patterns, but at a fundamental level the act of writing music is about making choices, and theory isn't. Sure some theorist might label your progression i III IV or something, but that doesn't tell you whether it would have been better to write I vi IV V instead; that's the composer's job, not the theorist's.
As far as analysis of a G Bb C loop goes, it feels like a familiar G minor blues progression to me; i III IV, but you're substituting a major chord for the tonic. If it was me, I might even turn them all into dominant seventh chords (or at least the IV seems like it's begging for it).
