i'm wondering if there are rules for the order in which chords are played in a given key.For example,is a vi I vi I progression ok?such as in the key of B which would be changing between the chords G#m and B.This is just an example.
I guess what i'm asking is,is it ok to play chords in what ever order i want as long as the chords belong to the same key?Or are there chord progression rules against this?
