This transcription was originally made and intended for oboe, but is also playable by flute in which case the 8va markings and the ossia at the end of the last movement should be used.
The sources of the themes used in the Concerto are: Movement 1) Stabat Mater, 2) & 4) Twelve Sonatas for two violins and bass, and 3) Song "Se tu m'ami".*
This edition was originally published in 1937 by Oxford University Press. This new edition has been re-typeset but is otherwise unchanged.
Pergolesi was born in Iesi, Italy and studied there under a local musician before going to Naples in 1725 where he studied under Gaetano Greco and Francesco Feo. He was an important early composer of opera as well as writing sacred choral works and secular instrumental works. He died of tuberculosis at the age of 26.
*There is now some doubt as to whether the song "Se tu m'ami" was actually written by Pergolesi and it is now more often attributed to Alessandro Parisotti (1853-1913).
