Simply put, this option helps you to find music that was originally, or at least thoroughly, intended for a member of the clarinet family. It will also meet the needs of any pianists who wish to remove orchestral/large ensemble reductions from their consideration.
While re-conceptualizations of previously-composed works provide valid and appreciated variety to our musical culture, some users may have a particular reason to exclude these types of works from their search. Terms used to describe re-conceptualization of music include transcribe, arrange, reduce, orchestrate, adapt, rework, and set; this filter merely uses the label "Transcription/Arrangement" for its easy recognition. CAMco's filter deals with the following cases:
Change in instrumentation
examples:
- Piano reduction of a larger ensemble score
- Reassignment of the solo part from non-clarinet to clarinet, like Sarasate's Zigeunerweisen performed with clarinet in place of violin
- New instrumentation of a previously-existing clarinet work, like the arrangement of Finzi's Five Bagatelles (originally clarinet & piano) for clarinet & string quartet
If a change in instrumentation was executed or personally sanctioned by the composer, then the piece is not classified as a transcription/arrangement.
examples:
- Benjamin's Le tombeau de Ravel was first written for viola, and later reworked for clarinet by the composer's wishes with the assistance of Gervase De Peyer
- Debussy's Première rhapsodie was first written for clarinet & piano, and later the composer re-orchestrated it for clarinet & orchestra
Reworking of previously conceived material
examples:
- Setting of a church hymn or popular song
- Movie themes adapted for solo clarinet and digital audio accompaniment
An exception is made for adaptations of material with an unknown composer, i.e. traditional folk music. In these cases, if the re-conceptualization is more "substantial" via new thematic material, restructuring, reharmonization, or other compositional development, then it will not be classified as an arrangement.
examples:
- JeanJean's Carnival of Venice (which adapts a Neapolitan folk tune), is not classified as an arrangement
Digital accompaniment audio is only classified as an arrangement if the recorded instrument(s) or work itself are classified as such (ex: a recording of a piano reduction).
