Johnny Richards was an American jazz arranger and composer scoring numerous sound tracks for television and film. He was a pivotal composer/arranger for cutting edge, adventurous performances and recording sessions by Stan Kenton's big band in the 1950s and early 1960s; such as Cuban Fire!, Kenton's West Side Story and Adventures in Time.

In music, an arrangement is a musical adaptation of an existing composition. Differences from the original composition may include reharmonization, melodic paraphrasing, orchestration, or formal development. Arranging differs from orchestration in that the latter process is limited to the assignment of notes to instruments for performance by an orchestra, concert band, or other musical ensemble. Arranging "involves adding compositional techniques, such as new thematic material for introductions, transitions, or modulations, and endings. Arranging is the art of giving an existing melody musical variety". In jazz, a memorized (unwritten) arrangement of a new or pre-existing composition is known as a head arrangement.
