A fairly common practice in the Baroque era was for organists to "borrow" and transcribe orchestral music from themselves or other composers to create spectacular organ solos. J.S. Bach adapted several works by Vivaldi-this particular transcription was originally for solo violin and string orchestra. The brilliant showy solo line interspersed with tutti sections lent itself well to the colours of the organ and now to brass. This is a trumpet feature with the quintet trumpeters playing running duet lines in support of the soloist. This is a version of this piece arranged in Bb concert. It facilitates performance on Bb trumpet rather than piccolo which makes this popular piece accessible to more quintets. For the original key please order BQ25200.
