| Infantas (1579), 11: Duo. | Textless canon by inversion. The canon is placed at the very end of the opus and is not a setting of the Gregorian chant «Laudate Dominum omnes gentes». The original print gives the performers no hints about the nature of this canon the fact that it may be performed exchanging the order of the parts. The two versions end respectively in E in F. |
| Cerone (1613) | Cerone included this enigmatic canon in a chapter of his Melopeo entirely dedicated to this matter and gave a thorough explanation of the solution. See also Bornstein, Italian Duos, vol. I, p. 131-34. |
