The American Federation of Musicians defines arranging as "the art of preparing and adapting an already written composition for presentation in other than its original form. An arrangement may include reharmonization, paraphrasing, and/or development of a composition, so that it fully represents the melodic, harmonic, and rhythmic structure" (Corozine 2002, p. 3). Orchestration differs in that it is only adapting music for an orchestra or musical ensemble while 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" (ibid).

Arrangements and transcriptions of classical and serious music go back to the early history of this genre. In particular music written for the piano frequently underwent this treatment.^{[citation needed]} The suite of ten piano pieces Pictures at an Exhibition by Modest Mussorgsky, has been arranged over twenty times, perhaps the most famous and notable being that of Maurice Ravel.^{[citation needed]}

Miles Dewey Davis III (May 26, 1926 – September 28, 1991) was an American jazz musician, trumpeter, bandleader, and composer. Widely considered one of the most influential musicians of the 20th century, Miles Davis was, with his musical groups, at the forefront of several major developments in jazz music, including bebop, cool jazz, hard bop, modal jazz, and jazz fusion.

Miles Dewey Davis was born on May 26, 1926, to an affluent African American family in Alton, Illinois. His father, Dr. Miles Henry Davis, was a dentist. In 1927 the family moved to East St. Louis, Illinois. They also owned a substantial ranch in northern Arkansas, where Davis learned to ride horses as a boy.

Davis' mother, Cleota Mae (Henry) Davis, wanted her son to learn the piano; she was a capable blues pianist but kept this fact hidden from her son. His musical studies began at 13, when his father gave him a trumpet and arranged lessons with local musician Elwood Buchanan. Davis later suggested that his father's instrument choice was made largely to irk his wife, who disliked the trumpet's sound. Against the fashion of the time, Buchanan stressed the importance of playing without vibrato; he was reported to have slapped Davis' knuckles every time he started using heavy vibrato. Davis would carry his clear signature tone throughout his career. He once remarked on its importance to him, saying, "I prefer a round sound with no attitude in it, like a round voice with not too much tremolo and not too much bass. Just right in the middle. If I can’t get that sound I can’t play anything."Clark Terry was another important early influence.^{[citation needed]}
