Hey cool, I was considering asking here for a good online lesson system....
I have a good feel for left/right hand coordination, I can play violin, and have a good ear, and an understanding of violin that I can't describe and don't understand my self, because I have played my whole life but have NO understanding of musical theory.
So without that theory, picking up my guitar and playing more than single notes proves hard.... and my fingers are fine on a violin with close notes, but frets and the distance between them can prove a problem for me. I need to learn about chords, and how to pick the right ones, etc.
Get used to blistered fingers, they're half the fun
*edit* it's cool enough that I paused flogging molly's tobacco island to listen to you, too
Do you have any prior musical experience? If not, or depending on the instrument, that's really really good for this soon.
