jazz music has a swinging rhythm. the word "swing" is hard to explain. for a rhythm to be a "swinging rhythm" it has to feel natural and relaxed. swing rhythm is not even like a march. there is a long-short feel instead of a same-same feel. a "swinging rhythm" also gets the people who are listening excited, because they like the sound of it. some people say that a "swinging rhythm" happens when all the jazz musicians start to feel the same pulse and energy from the song. if a jazz band plays very well together, people will say "that is a swinging jazz band" or "that band really swings well."
