Variously known as Il Cardellino [ Italian] or Il Gardellino [Venetian dialect] or The Goldfinch) [English], the Concerto in D (op.10.no.3 rv.428) takes its name from the many trills and scales abounding in the first movement, that sound like the twittering song of the little bird.
the flute duet version comprises the flute solo plus an alternative accompaniment, that has been compressed into a single line for a second flute player.
