I have found that what is really a blast is to play music rather than to listen to it.
I started out performing country music in grade school, then in high school I played rock and symphonic music (our "school band" was a symphony orchestra; such luck!). These days, I play early (medieval and renaissance) music. I love the intricacy, amazing ingenuity, and the wonderful beauty of early music.
I have heard that one's taste in popular music gets set in high school. I really like folk rock and acid rock, so you can guess my age.
Just for curiosity, does anyone else find that a lot of current pop songs lack decent melodies? I hear very few songs with tunes that one might whistle later. I wonder why that is.
I noticed some time ago that scientific and technical people are often keen musicians. The early music group I play in are all scientists and medical people, and many other scientists I have known have been musical. This seems unexpected somehow.
