Castello’s Sonata 15 is typical of the early Italian solo and ensemble sonata of his time -- the entire work consisting of a single movement with several sections of different tempi and meter.  This transcription for recorders is based on the original part-books of 1644 and 1629. The piece has been transposed down a fourth from D to A to fit a recorder consort of soprano, alto, tenor and great bass (in C). An alternate part for the bass recorder is provided for those ensembles that lack a great bass.
