I used to have an acoustic guitar, for a brief time. I learned the Come as you are bass riff, and the solo for teen spirit. I broke the neck and gave the Nirvana guitar book to my bro. I am strictly all Keys now, keyboard keys. I've had a keyboard since I was ten, still got the Yamaha PSS-170 that I learnt on. I found it a lot easier to learn music theory on the keyboard. At first I didn't understand the theoretical vs practical side of music and how they related. Now I know!
I like classical mainly because it suits keyboard and is very melodical. It is also one of the most difficult. I can play a good Bruce Hornsby i will have that up on youtube soon. I'll teach mofo's how to play.
