I love jazz too. I think what draws me the most to it (and also to alot of folk and bluegrass) is the improvisation. Not only is it impressive to me that people can improvise in music together so well, but i find it very easy to get caught up in a peice that is improvised. I start to feel what the artist is feeling and my energy levels will, during the course of a jazz cd or song, match those of the music. I will often put on some upbeat jazz when i am trying to finish a term paper or put on slower, more mellow stuff when i come back from a workout to help slow me down. For me Jazz and folk music together comprise the music of life, because in a sense, it is alive. No other kind of music touches me like they do.
