In the 1560s Alessandro Striggio composed monumental works such as his Missa sopra Ecco si beato giorno à 40 and a 40-voice motet, both of which can be proven to have been performed in Munich in 1567 and 1568. Analysis of the performing forces of Munich’s Cantorey of this time concludes not only that the instrumental participation of these performances must have been significant, but also that the works were transposed downward. Furthermore, a hypothesis is proposed that the Munich performance of an untitled 40-voice motet in 1568 involved Striggio’s Ecce beatam lucem à 40, which itself may constitute a contrafactum of Ecco si beato giorno, a madrigal that circulated in copies during the decade.
