In spring 1999, almost a decade ago, the first author published in The Sport Journal an article titled "Music in Sport and Exercise: Theory and Practice." The present article's origins are in that earlier work and the first author's research while a master's student at the United States Sports Academy in 1991-92. To a greater degree than in the original 1999 article, this article focuses on the applied aspects of music in sport and exercise. Moreover, it highlights some new research trends emanating not only from our own publications, but also from the work of other prominent researchers in the field. The content is oriented primarily towards the needs of athletes and coaches.
