Hi Chris. I'm Chris as well. I play piano. I'm self taught piano player.I leant by reading piano chord books.Now there are websites that show piano chords and even piano chords in any key. I use those sites to learn which chords go with which key.
I learnt to press each chord first.After awhile I learnt how to move my fingers with each chord so I play each chord.That was the easiest way for me to learn.I still cant read music but as long as I know the chords I can write music and play music.
Thanks for posting a great topic.
