Identifying the music in 2001 requires distinguishing who composed each work from who performed the recording that is heard. Reissues add another complication: they do not always reproduce the film’s exact edit.
A Musical Work Is Not a Specific Recording
The soundtrack of 2001 uses preexisting compositions by Richard Strauss, Johann Strauss II, György Ligeti, and Aram Khachaturian. Each name identifies the author of a work, but it does not automatically identify the orchestra, conductor, or sound recording used. The same composition can exist in many recordings with different durations, balances, and interpretive choices. The film selects excerpts and integrates them into specific scenes, so proper attribution must consider both the work and the recording.
The analysis of the musical selections examines their cinematic function, while this article focuses on documentary identification. A composer credit in a promotional list must also be distinguished from the information provided in a record release. An album may bring together recordings from different sources and present complete tracks that do not match the excerpts heard onscreen. To compare recordings, identify the date, label, and credits of the specific release rather than assuming all reissues are equivalent.
Strauss, Ligeti, and Khachaturian: Credits That Must Be Kept Separate
An official 2018 release of the film’s music credits, among other recordings, Karl Böhm with the Berlin Philharmonic for the prelude to Richard Strauss’s Also sprach Zarathustra, and Herbert von Karajan with the same orchestra for Johann Strauss II’s The Blue Danube. Different performers are listed for Ligeti’s works: Ernest Bour for Atmosphères, Francis Travis for the Requiem, and Helmut Franz for Lux aeterna. These details show why simply listing the composer’s name is not enough.
The release also identifies Khachaturian’s Adagio from Gayane, in a recording conducted by Gennady Rozhdestvensky with the Leningrad Philharmonic. The use of the adagio in the Discovery belongs to scene analysis, not to the recording’s catalog entry. Ligeti’s music requires a similar distinction between different compositions by the same author. Credits can vary from one edition to another and should always be cited alongside the release that provides them.
The distinction between composition and performance can be demonstrated with specific examples. Richard Strauss wrote Also sprach Zarathustra, and Johann Strauss II composed The Blue Danube; sharing a surname does not make the works part of the same authorial tradition. The official 2018 release identifies Karl Böhm as the conductor of a recording of the former’s prelude and Herbert von Karajan as the conductor of the waltz. The orchestra conductor’s name belongs to the performance credit, not the composition’s authorship. An accurate music catalog entry should keep these in separate fields and, when documented, add the ensemble that made the recording.
Ligeti’s work presents another challenge. The film uses more than one of the composer’s works, and a reissue may credit different performers for Atmosphères, Requiem, and Lux aeterna. It is incorrect to speak of a single Ligeti recording as though it contained all of his music in the film. The works have different structures and sound sources, and the edit selects excerpts for specific situations. Documentary identification can indicate who performed each piece without turning that information into an explanation of the monolith or the Stargate. That interpretation belongs to scene analysis.
Comparing the film with the album requires listening, not just reading track titles. A commercial track may present the complete work, while the film uses only a passage. Reissues may also have different track orders, durations, or credits. Record labels and rights holders are part of the recording’s material history. Correct attribution avoids confusing music composed for a film with preexisting music selected for it. In 2001, this distinction is especially relevant because Alex North’s original score was rejected and the released version retained a selection of previously recorded works.
From the Film Edit to the Album
The music heard during a screening does not have to match the length of a track on a record. A piece may start at a different point, stop before the end, or be mixed with other sounds. Albums may also include complete recordings or alternate versions intended for listening on their own. That is why a track list alone cannot prove exactly which excerpt appears in each shot. Comparison requires listening to the identified copy and checking it against the attributed recording.
The study of Ligeti’s permissions and claims addresses another dimension: authorization to use a work or a recording. Identifying a composition does not prove that all rights had been cleared by the time of the film’s release. Musical attribution in 2001 requires separating the work, performance, release, and cinematic use. Keeping these levels distinct prevents common mistakes, such as confusing the two Strausses, assigning one orchestra to every piece, or treating a modern reissue as an exact copy of the original soundtrack.
A music release’s catalog entry should also indicate whether it contains a complete track or an excerpt. Two releases with the same work title may differ in duration and editing. This precision makes it possible to compare records and the film without automatically attributing all the content of a reissue to the version released in theaters.
