Guitar!
 

It matters not whether you win or lose; what matters is whether I win or lose.

I'd like to learn more classical...

I don't suppose you know much about left-handed playing, do you?

I know everywhere just says "play the chords the opposite way round", but I'm forever getting mixed up.

lol, that sounds really silly Lenny. "Play the chords the opposite way round." Could they be any more obvious?

That's what my sisters guitar book says, and quite a few sites on the web.

Look for "Southpaw Guitar" or "Southpaw style" or something. It pretty much just means left-handed style.

The internet helped me a lot in learning to play.
