Since many musical works have generic titles, such as concerto, symphony, sonata, etc., narrow your search in Scholar by using a keyword search with specific information.

This will retrieve scores and sound recordings of Hindemith's Sonata for violin and piano, op. 11, no. 2. The piece may be a score, in an anthology of recorded pieces or one of several pieces on a recording.
2. Using the same search string in the button, limit your search to "music record" in the "Material Type", this retrieves the recordings of Hindemith's Sonata for violine and piano, op. 11, no. 2.
3. To search and gather all the scores and recordings of a composer, search as Author, using the composer's full name, such as, Hindemith, Paul. This search will retrieve all items where Paul Hindemith is the author/composer (scores, recordings, books). The results are ordered by title and provides alternate forms of the title, which lead to the title used in the catalog.
