Key Changes

I was just wondering if i were to play in any given key, say c to make it easy, what are my options for changing keys? I know i could play in A minor because it is it's relative and i understand all the theory behind that but i was wondering if there was a theoretical approach to finding all possible options of keys to change to.

Chord Frustration

For some reason i have an extremely bad writer's block and every time i try to write progressions i toss them all out due to the fact that everything i play just seems to sound the same and circle of 5ths-ish. I recently tried to expand my chord vocabulary by learning diminished, suspended, augmented, 6, 9, and a few others. Despite working these chords into my songwriting, i still cant seem to get the sounds i want sometimes. I try to reshape the chord note by note to create more interesting voicings but i cant ever seem to come up with anything. I was wondering if there was like a good order of learning chords. I have my open, barre, a couple inversions, and the chord types i mentioned earlier under my belt but i would like to know what else i should be trying to memorize. Thanks for your help. Sorry if this is kind of confusing. I'm awful at organizing my thoughts in message board posts.

Still Accepting?

Hey guys. I was just wondering if the mentor program is still open to applicants. Sorry if this has been answered somewhere but i'm on a painfully slow computer and cant browse posts at the moment. Thanks! -Nick
