The Witness doesn't have a soundtrack in the traditional game sense, but several compositions can be heard in its hidden corners. This is a compilation of them. 0:00 - Finale (Conclusion), from Béla Bartók's Concerto for Orchestra. |--| In The Witness, part of this song plays at a reduced speed and pitch at the end of the Connections clip. |--| It's difficult to tell which recording the show uses, so I somewhat arbitrarily chose this one by the Baltimore Symphony Orchestra. 9:41 - Introit and Kyrie (Entrance and Lord), from Giuseppe Verdi's Requiem. |--| In The Witness, part of this song plays with subdued vocals toward the end of the Nostalghia clip. |--| It's even more difficult to tell which recording the film uses; this one is by the Kirov Orchestra. 18:23 - Kumushki (Godmothers), a Russian traditional song. |--| In The Witness, part of this song plays at the end of the Nostalghia clip. |--| This recording, which I believe to be the one in the film, is by Olga Seergeva. 20:48 - Anitras dans (Anitra's Dance), from Edvard Grieg's Peer Gynt. |--| In The Witness, this song plays when you activate the challenge. |--| I'm not positive whether this Musopen Symphony recording is the one in the game, but if not, it sounds close. 24:48 - I Dovregubbens hall (In the Hall of the Mountain King), also from Peer Gynt. |--| In The Witness, this song plays after Anitras dans. |--| This recording is also by the Musopen Symphony. 27:22 - Die Kunst der Fuge (The Art of Fugue), Johann Sebastian Bach. |--| In The Witness, this song plays over the Brian Moriarty talk. |--| My understanding is Moriarty produced this recording on a virtual piano, then trimmed it a little to fit the lecture.
