Ok so im trying to gain some understanding... So pregressions.. AB, AABB, ABAB, AABBA ect Im having a hard time relating that to building a pregression. Im not even really sure im on the right path or not. Im familiar with ionian and aeoleon, triads, intervals, relatives, modes. Im trying to put all that knowledge to work . Can anyone give me a push in the right direction? Maybe be an example?
