I was looking into taking guitar lessons. My question is, does it matter what kind of music the teacher mostly plays? i.e. Jazz, Classical
If I want to play primarily heavy metal, hard rock, classic rock should I look for a teacher who plays those styles?
Or is it as long as the teacher is good, it really doesn't matter what style of music they are into?
Any good teacher is generally going to help you understand the foundational elements of music - theory, essentially. Scale tones, modal systems, harmonic interaction, proper timing, probably phrasing... all useful.
The trick is with licks and typical 'patterns,' if you will, that are in every guitar player's arsenal. Jazz licks and really, the whole approach to how to integrate that basic knowledge into a musical context, will be very different from a traditional blues/rock approach.
That's not necessarily a bad thing, though! Alex Skolnick is one badass metal shredder, but he is a really good traditional and fusion jazz guitarist, too. I studied classical guitar in college. Very traditional. And I don't use that shit much anymore. But the foundation I received is always useful in whatever I do musically.
