So my band just got a new drummer and he's kick ass! I've learned so much about rhythm from him but I feel kinda stuck in a rut. I know how to groove like a machine but when it comes to chord progressions I don't know where to go other than 1-4-5... let's say I'm grooving in A Major giving it lots of rhythm and funkiness but it sure isn't a song yet. It gets boring after a while and I can only imagine the frustration the guitars would have just playing A major... any suggestions?.. I heard once something about chord substitutions.. tritone substitutions, and 3-6-2-5-1's and jazz blues progressions.. if anyone knows anything about that stuff Thanks, in advance, for your replies!
