Well, Steve Vai joined my dads band right around the time when I actually started playing guitar. So he gave me a couple of lessons on fundamentals, and gave me some scales and practice things to work on. But I pretty much learned everything by ear. – Dweezil Zappa

And, you know, my dad would show me some things sometimes, but the best things that I got to do were to actually see really good players play up close. That gives you an idea of fingering and technique and what not. – Dweezil Zappa
