Day in multiple movements

The Hours is the original soundtrack album, on the Elektra/Nonesuch label, of the 2002 film The Hours. The original score was composed by Philip Glass.
Not all of the music in the film was composed specifically for it: earlier music by Glass, including a theme from his opera Satyagraha, was also featured and credited separately at the end of the film.
Michael Riesman and Nico Muhly arranged the soundtrack for piano solo. This score was published in 2003 as a 64-paged book containing most of the tracks.
