[textless duo in F]

| Gumpelzhaimer (1591), 6: Iosqvinus. | This brief duo is employed as example of mensural proportions in the chapter «De Proportionibus». There follows the solution: «Sequuntur resolutiones illarum vocum». The musical incipit of this duo is quite similar to that of the duo – again attributed to Josquin – that took the place of the former duo in all the following editions and reprints of the treatise. See Gumpelzhaimer (1611), 1. |
