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.

Example:

Search as keywords: Hindemith sonata violin op 11

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.
