I love to play the piano. I'm not very good at it but I could play for hours and hours on end and I sometimes do.
I don't know if there is such thing as a musical paradigm but I think I grew up in one. Both my parents sing well and we've always had a piano (which we beat the crap out of over the years). Growing up, singing and fooling around on the piano has always been part of what we do to connect as a family.
Nowadays, if I go too long without the harmonious chords of a piano, I've noticed I start getting itchy fingers. When I get itchy fingers, I can hardly walk by a piano without giving into the urge to sit down and play.
