跨界音乐("Crossover" Music)是一种新的音乐型式。富变化性质且平易近人。

有多种定义的方式，范围很大。

举例说明，古典音乐的曲目重新诠释成不同的演奏手法、流行乐手演奏古典音乐，都可以算是跨界音乐的一种。

比如：意大利男高音安德烈·波伽利，英国女高音莎拉·布莱曼，新西兰女高音海莉·薇思特拉等同属古典音乐与流行音乐的跨界歌唱家。

Crossover is a term applied to musical works or performers who appeal to different types of audience, for example (especially in the United States) by appearing on two or more of the record charts which track differing musical styles or genres. If the second chart combines genres, such as a "Hot 100" list, the work is not a crossover.
