Libro 1 includes 5 full diminuateted pieces composed by Cipriano. Another pieces are partly arranged. So I'll entry 5 full arranged pieces only.
Original of 5 pieces by Cipriano are included in "Tutti i Madrigali di Cipriano di Rore a Quattro Voci"(1577) published by Angelo Gardano.
No.1 "Io canterei d'amor" ; This is an easier piece.
