The presiding myth is that we are stamped with our timbal fingerprint. We can only sound as we sound. That seems to be true. But I am wondering if I can go against this axiom... and some teacher knows the bass so well that he can teach how to get truly different sounds . I am not talking about pedals, and strings, just our basic tonal conception, as our finger strikes the string. I had a sax teacher who knew the sax so well ( he taught almost everyone in NYC at the time ) that you could learn how to alter your fingerprint so to speak. Anyone have a bead on this?
