One soloist will speak for himself on a chosen topic and then retire to hear the feelings of another on the same subject. On occasions, they will speak of happy things, then those of a more serious nature, sometimes somber and even tragic. All phases of life's emotions are felt and experienced in jazz. Some of the music is complex and reaches far below the surface while other forms dwell lightly. There are speakers in improvised jazz who are eloquent in their ability.
Musical words flow freely.
Others tend to speak in short sentences with a simple vocabulary. However, if sincerity prevails, everyone is felt, understood and appreciated. Despite this excellent description of jazz by Kenton, we are still left without an adequate working definition of jazz. If a man has some very hungry ears for what he considers jazz, or for a pleasant noise that makes him feel he wants to swing, that's jazz. Jazz is what you or I say it is.
