mate, being tone deaf is very rare indeed. It literally means, being unable to distinguish the pitches of two different notes... as being different at all - i think it has physical root
you are almost certainly not tone deaf
not being able to sing is nothing to do with it, i am exactly the same, can't sing for shit![]()
sometimes, tone deaf is used by music teachers to mean people can't sing, maybe that's where you got that from??
