I've taken like 3 lessons from a DB by the name of Sarah DeMarco, a local, very good DB player in my area to try to learn DB after playing EB. It only took me about 1-2 weeks to learn pizz, which seems about right since it is fairly similar to EB, but I'm just now starting to get the hang of arco. I am currently a 10th grader and playing in our class A instrumental group and from what I can hear of myself, I sound decently good. I was wondering if I should find another local teacher (Sarah doesnt give lessons anymore) to continue my double bass playing experience, or just keep doing what I'm doing and pick it up on my own. I dont own my own bass (Use one of the school's decent basses), so that might be a problem to take outside lessons...Was just wondering on your guys thoughts...thank you.
