Charlie and the Chocolate Factory (film) shades of chocolate were tested before Burton settled on the proper hue. The original music score was written by Danny Elfman, a frequent collaborator with director Tim Burton. Elfman's score is based around three primary themes: a gentle family theme for the Buckets, generally set in upper woodwinds; a mystical, string-driven waltz for Willy Wonka; and a hyper-upbeat factory theme for full orchestra, Elfman's homemade synthesizer samples and the diminutive chanting voices of the Oompa-Loompas. Elfman also wrote and performed the vocals for four songs, with pitch changes and modulations to represent different singers. The lyrics to the Oompa-Loompa songs
Charlie and the Chocolate Factory (film) are adapted from the original book, and are thus credited to Roald Dahl. Following Burton's suggestion, each song in the score is designed to reflect a different archetype. "Wonka's Welcome Song" is a maddeningly cheerful theme park ditty, "Augustus Gloop" a Bollywood spectacle (per Deep Roy's suggestion), "Violet Beauregarde" is 1970s funk, "Veruca Salt" is 1960s bubblegum pop / psychedelic pop, and "Mike Teavee" is a tribute to late 1970s hard rock (such as Queen) and early 1980s hair bands. The original motion picture soundtrack was released on July 12, 2005 by Warner Bros. Records. "Charlie and the Chocolate Factory"
