I just
had to respond to this older thread. I hope that someone will read it even though I'm responding some five years after the last post.
For me, my high school jazz band experience was great! Our first jazz band teacher was, of all things, a violinist! When you walked into the band room, sometimes you'd hear him playing a classical piece, such as the
William Tell Overture, while he strolled around. Then, he would switch to playing jazz improvisation on his violin.
That example in itself made me very interested in being able to play many kinds of music -- and since I was a college prep music education student, by the time I was in the 12th grade, I had learned virtually all of the band and orchestra instruments.
In high school, my main instruments were trumpet, baritone sax, flute and piccolo, and piano.
About a year before I graduated, we got a new jazz band teacher, as the previous one spent more time with the strings and orchestra classes. This new teacher was an experienced studio musician, who played jazz alto sax, jazz piano, and Latin jazz. He was also a composer.
These great jazz experiences in high school motivated me as an adult to continue to play jazz, as well as to broaden my horizons, to be able to play various styles as my exemplar teachers had been able to.
Even though I've been a working adult with a couple of careers for three+ decades, I still play jazz as well as many other styles. Whenever I can, I get together with some local jazz musicians, just to jam.
As a result of those fine musical examples in high school, I have learned to play--in addition to jazz--classical (notably
Rhapsody in Blue), Broadway shows, pop, rock, movie music and TV themes, sacred music, and so on. I play both by ear and with printed music.
Nevertheless, for me, jazz will always be a part of me!
