I was a bit in doubt whether this would belong in the beginners/faq forum, but the hell, I guess it's a pretty complicated matter of musical theory. Let me sketch the picture as simple as possible, I have a tendency to build my songs around a single scale, mostly the minor scale. So the song would consist of some riffing and a bit more chord oriented parts for the choruses. My older work would often find both starting with the key of a scale and progressions would be mostly diatonic. I have been trying to divert from starting chord progressions in the scale's key, but in a minor scale starting on a 5th or 6th sounds best, so I almost always revert to those notes as the root for a chord. Frankly, I'm getting a bit sick of always reverting to those patterns. I try to divert by switching the key scale, which sometimes is nice, but still, it could be more interesting. I have experimented with just moving up to a different scale in a different key, to make it non-diatonic, but I often have trouble making things come together as a song. Now here's where I need some advice: what are interesting and good sounding switches in key and scales while retaining that feeling of coherence between sections? Just to keep it a little bit simple, I would like to discover things around using minor/major scales. I don't really need to go in Jazz territory.
