I first started playing in piano bars for three reasons - to make money, to be in the company of my friends - and also to hook up with young girls. I always knew, even before I played in piano bars, about the effect of my voice.
Music is a prerogative of those who are willing to spend time to study it, understand and love it, well aware of the fact that one life is not enough to improve just one single note of what has already been written and performed.
Listen to what others tell you about your voice. If you're only singing to please yourself, you might as well just sing under the shower. But if you're singing for others, you are reliant on them to ask you to sing.
I listen to music every day for study reasons, and I confess that I have very little knowledge of what is going on in the hit parades around the world. I have no prejudices for any kind of music genre, and I listen with pleasure to many songs on the radio that my children already know of by heart, while I hear them practically for the first time.
