I was born with my left hand cut off at the wrist. I can't really play very many instruments, seeing as how it would be nearly impossible. This may seem like a very weird question, but I was wondering if it's possible to play the double bass using my left wrist. I understand that the bass is played one string at a time, does this mean that it only takes one finger on a string to play a note? And, without a thumb on the left hand to support the bass, would the bass fall over if only supported by my body (or perhaps some sort of stand)? I decided I need to talk to some actual bass players to figure some of these thoughts I'm having out, as an upside-down guitar is the only thing I've had to sort of test my thoughts. I know even if I could handle playing some bass, I wouldn't be very good but I don't really care. Right now I'm just trying to figure out if playing the double bass is physically possible at all. Thanks to anyone who gives me some opinions or knowledge on the subject. Any questions anyone has, I'll answer.
