You can formulate your search to provide with an overview of relevant works.
Music has many variations of format of subject headings - including an arrangement of a work originally written for, say flute, but arranged for another instrument.
You can develop a listing of specific instrumental repertoire that the Library holds, by developing your listing through sequential searches.
For help searching see also the Music Guide:
Music subjects use standardised formulae based on instrumentation and musical forms.
Some subject headings begin with the major musical instrument: e.g. Bassoon music (works for bassoon solo), or, Saxophone music (Saxophones (2)) (works for sax duet), or, bassoon and piano music.
Some music subject headings begin with the musical form: e.g. Concertos (Piano), or, Sonatas (Clarinet and piano), or, Suites (Woodwind ensemble).
