Vocalese, coined by Jazz critic Leonard Feather, is the art of composing a lyric and singing it in the same manner as the recorded instrumental solos. Vocalese reached its highest point from 1957-62. Performers may solo or sing in ensemble, supported by small group or orchestra. Bop in nature, Vocalese rarely ventured into other Jazz styles and never brought commercial success to it's performers until recent years. Among those known for writing and performing Vocalese lyric are Eddie Jefferson and Jon Hendricks.
