Canon à 6 - Agostini, Paolo 1583-1629 (1627)
Notated on two staves. Duces only, with presa signs indicating entries of comites. Each staff has double barlines and repeat marks, indicating circle canons. On page 7, the first staff has an upside-down treble clef at the right-hand side of the staff, indicating that the second version of the melody on this staff involves retrograde contrary motion (i.e., the comes in solution 2).
First two solutions based on the natural hexachord, third solution based on the hard hexachord. Solution 2: (i) the comes observes the reverse treble clef and the three breve rests before starting the retrograde of the dux up a compound fifth (19th) from the final note of the dux. (ii) All other voices in this canon are the same as in solution 1. (iii) The overall result is that the comes in solution 2 is the same as the comes in solution 1 except that it (comes 2) is an octave higher and begins one bar later. The third solution is notated on page 8. Translation of rubrics on page 7: With the observation of counterpoint at the 12th and with three solutions ["modi"]: [1] as given over la, sol, fa mi, re, ut. [2] the soprano sings five steps higher and begins on G sol, re, vt and sings without the other parts changing. [3] all parts are exchanged as can be seen on the following page. Four Altos who [each] sing one step lower. Translation of rubrics on page 8: Six parts. Canon derived from the previous version, with real reversal by turning the book upside down. The bass begins at the end and the other parts that before sang ons step lower now sing one step higher. Turned over.
