Took piano from about 7-16. Hated almost every minute of it (until the end when I started to play some Beatles songs). Mom, long since passed, always said one day you'll thank me for it. Lots of screaming at each other. But later, when I picked up the guitar at about 16 because some high school friends played, I caught up and passed them by the time we graduated. That was because of piano. Piano is the theory. In college, it allowed me to have a minor in music. To this day, playing guitar, if I envision a chord, I still visualize it as keys. A bass line, I see notes on a bass clef. I truly believe that if you can play piano you can then play anything. Even drums takes me back to piano lessons. I rarely touch a piano anymore, and I'm by no means a great guitar or bass player, but I think it made learning those instruments a lot easier and therefore a lot more enjoyable. Thank you Mom, you were right.
