I enjoy cooking for my friends, listening to jazz, singing and playing the piano, amassing useless antiquated trivia, going out dancing and cocktailing*, reading, attending ballets and symphonies, fine dining, and the kind of discussions that last until the middle of the night.
*The embedded editor doesn't believe that is a real word. I disagree. Perhaps after it has been cocktailing for a while it will see the light. The warm, fuzzy, slightly-blurred-around-the-edges light.
I've been playing piano since I was four years old, and have played nearly every brass instrument since then. My main instrument, though, is the voice. I'm a classically trained baritone, and a semi-professional vocalist.
B) My favorite movie when I was 5, and my favorite movie now, is The Dark Crystal. Other than that, anything that is epic and/or imaginative is great. If it takes 4 hours to watch, I'll probably like it (e.g. Cleopatra, LotR movies, et cetera). I'm also a huge fan of various genres of Foreign cinema: French fantasies (City of Lost Children, Amelie), Chinese epics (The Emperor and the Assassin, Hero), any of the Kurosawa films, and a great many anime movies.
C) Being a musician, it's hard for me to dismiss any type of music. However, it is a very rare day when you'll catch me listening to Country or some of the more vapid Ultra-Pop. I'm primarily interested in Classical and Jazz, with Rock being a common mainstay. Since I love to go dancing, Latin, Techno, and anything else that has a good beat is always fun.
D) Cooking is a bit of a hobby of mine. I host dinner parties on a regular basis. And, so, my tastes are many and varied. Generally speaking, I prefer to push the boundaries: trying new cuisines, new foods, and new expressions of old standards.
The "most private" is of broad scope and highly dependent on the individual- from announcing your heretofore secret disdain for plaid fabrics to displaying photos of your recent colonoscopy.
(For the record, I am generally in favor of tartans, yet typically dislike madras, and have impeccable gastro-intestinal health.)
