elmore, I'm a shy singer...strictly shower and car and places where the world at large cannot hear me...though I do it all the time. The Lovely Wife, the real vocalist in the family, is always very complimentary and encouraging, telling me I have a nice voice. She heard me whistling a rather complex Miklos Rozsa piece once (I'm a very good whistler...eat your heart out, Muzzy Marcelleno and Elmo Tanner) and said: "Let me hear that again." After I complied she commented: "Just as I thought. You have perfect pitch." How she knew this, whether it's true or not, and just what perfect pitch is, I have no idea.
