The original soundtrack to Amadeus reached #56 on Billboard's album charts, making it one of the most popular recordings of classical music ever. All of the tracks were composed by Mozart, save an early Hungarian folk tune and the final movement Quando Corpus Morietur et Amen by Giovanni Battista Pergolesi, from his famous Stabat Mater.
The film features some music that is not included on the original soundtrack album release. As stated above, except where specified, all tracks were performed by the Academy of St. Martin in the Fields, conducted by Sir Neville Marriner, and all were performed specifically for use in the film. According to the film commentary by Forman and Schaffer, Marriner agreed to score the film if Mozart's music was completely unchanged from Mozart's original scores. Marriner did add some notes to Salieri's music that are noticeable in the beginning of the film, as Salieri begins his confession.
Music featured in the film but not included on the soundtrack album (but included in a later extended version):
- The Magic Flute, overture
- The Magic Flute, "Das klinget so herrlich"
- The Magic Flute, Queen of the Night aria ("Der Hölle Rache") performed by June Anderson
- The Magic Flute, "Ein Mädchen oder Weibchen..." (Papageno) and "Pa-pa-gena! ... Pa-pa-geno!" (Papageno and Papagena) performed by Brian Kay and Gillian Fisher
