The composer of this song, Pietro Paolo Bencini (1700-1755) is known principally as the Maestro di Cappella at the Sistine Chapel in Rome, and as the composer of a large number of sacred works of high merit. Most of his compositions sleep peacefully on the shelves of the library in Rome.
Tanto sospirero (E’er will I sigh) is written in the most traditional style, and is a song of love. (from “Classic Italian Songs for School and Studio“, Volume I, M. Glenn and B. Taylor, editors, Bryn Mawr, 1936)
