Just looked at what the rest of you wrote, there's a lot of agreement!

I feel I have an exceptional tone, and have been told that by listeners both educated ("lovely tone") and "uneducated", sounds snotty, sorry can't think of a synonym ("you have a nice touch, kid")
The singing line on the percussive instrument is the harder of the two challenges imo; some pianists have a horrid tone but sing on the piano like Pavarotti (Schnabel and Serkin immediately come to mind) and others have a tone to make you melt, but are melodically unfocused (Bill Evans, Boris Berman, Pascal Roge immediately come to mind) but of course the ideal is to have both, AND a good technique...
