Gary ... Like you, vocals are a MAJOR part of my performances ... and, not to pay myself on the back, but I too have often been complimented on my voice ...
What I have noticed, is that people will not often say "You PLAY well", but rather, when it comes to the music part, at the end of an instrumental they might say "you have a nice sound" or "that was very pretty", or words to that affect ...
But I have said here many times, for the most part, the kb is there to back up my vocals ... while I can do a good job on instrumentals, I am not a 'piano player' and do not 'sell' myself as one ...
