I used to teach when I was a student.
It can be fun when in rare cases, people aren't forced into it by their mothers
I would imagine you:
A:Work well under your own steam (otherwise you wouldn't be a gearslut)
B:Probably don't need lessons every week 'cos of A
C:Can be given lots of stuff to do because you're adult and you want to learn
I could set you on the right path for the price of beer. If you need more after that I'd have a better idea of where you're going with it and could pass you on. Do you want to be able to read music more/better 'n all that, or just get your hands around the keys qucker? Or play Fur Elise at birthday parties and Bah Mitzfahs?
Best thing about doing grades (yes I know it sounds boring) is that you get something to work towards. I have tried to teach a lot of people who get out a Beatles chord book and don't want to learn scales. They usually don't learn nothing. No pain no gain!
Whereabouts are you in this stinky never-have-frikkin-summer rat hole city of ours?
