I've done some looking to no avail, so I'm hoping one of you will know the answer to my question. If I'm in a minor key and I play a i, iv, v progression, but later on I change ONLY the i to a major, how is that chord identified? For example, in A minor, if I suddenly played an A major, but still had a D and E minor following.
I don't know what to call it, other than a non-diatonic chord, but something tells me there's probably a name for this type of chord in this situation, as well as other non-diatonic chords. I haven't really studied post-tonal theory, so I wouldn't know where to begin. If someone could point me in the right direction, I'd appreciate it.
