Transcription in Baroque era 

The practice of transcription holds a prominent place in the baroque era, not only responding to a pragmatic interest that finds solved the problem of coming up with new musical ideas from scratch. Adapting and elaborating a musical idea to the possibilities and idiom of the new instrumental means poses an interesting task to the arranger, who must pick the essence of its content and transform it, making the new transcribed work autonomous in its own right. For example, J.S. Bach reinvents the Prelude of the Third Partita into the amazing Ouverture of Cantata BWV29, that featuring concertato organ, trumpets, strings and continuo, results satisfactorily autonomous from the violin version with which it shares its musical content.
