Here's the deal: I've never had bass lessons after noodling for a year, and I want some. I've been playing trombone for a decade, which means I have very strong bass clef sight-reading skills that translate well onto bass. I also know all the basic theory, as well as some not-so-basic theory. I'm familiar with the concept of "musicianship." Though phrasing, dynamics, and accents don't work quite the same on the two instruments, the concepts are old hat. I don't need someone to explain them to me, I don't need someone to explain to me how to read bass clef, and I don't need someone to tell me to assign one finger per fret and alternate fingers on my plucking hand. That said, I don't really know what I do need, which is why I need a teacher. I've found highly credentialed teachers who charge a lot of money, judging by the hourly rate thread ($90 and more per hour), and I've found less credentialed teachers who charge a lot less (say, $30 per hour). I had resigned myself to just paying $90/hour for a good bass lesson, but then I took a lesson with a guy who charged $30/hour. Clearly this guy hadn't quite earned his Music Education degree, but he worked with me on some stuff in a constructive way out of some books that he suggested I buy. It was informative, it was fun, I'll go back next week. I also signed up for a lesson with a guy in a music school who charges $90/hour, and after my lesson with the cheap guy, I have my doubts about following through with the expensive guy. I understand that you all can't see through my eyes right now, but can the guy who wants $90 really offer me a lesson that's three times as useful as the other guy? Is $90/hour a blatant rip-off? Or could it be the most illuminating hour of my life? And here's another thing: if I go to this lesson and I find after 15 minutes that the guy is a total jerk off, can I walk out? Pay him $20 and leave because it won't be worth my time?
