| Hey Mr. Scuzzy666 (frankly, I am frightened by your name alone):
Let me take this "find a teacher" thing just a bit further. You might be an experienced-bass guitarist, but playing the bass, as in contrabasso, is a whole different challenge. It is very different technically, physically and certainly requires a greater sense of intonation (none of those little metal strips on the neck to remind you of where you are at).
Anyway, the guys that offerred you advice previously are all qualified players, I on the other hand am relatively new to the instrument. I can tell you that a good teacher (classically trained) can get you up to speed pretty quick on the technical and physical aspects of playing. The rest is your responsibility.
Check with your local symphony to find out if any of those guys provide lessons. That would be your best place to start.
Good Luck. |
