I'm a natural piano player. So all the practicing I do at this point is in my head. If I don't play for a year, my chops aren't going to get any worse. I've spent my time playing scales, and I don't necessarily want to play any faster than I play. So everything I do at this point is more philosophical.
It is jazz music that called me to be a musician and I have always sang the songs that moved me the most. Singers, like Frank Sinatra and myself, we interpret the songs that we like. Not unlike a Shakespearean actor that goes back to the greatest words ever written, we go back to the greatest songs.
