We updated our Resources section with the six prophecies of the Vigil of Pentecost set to our chant tones! Go to said section and scroll down or just click on the image to the left. The tones used in this compilation, which we call Book II (even if it was produced two years before Book I), are identical to the ones used in said Book I, with the only exception of the tonus ammelleo-cynepurgilæticus (which was added only in 2017). Again, the idea behind the arrangement is decidedly iuniores ante seniores, that is, the chant becomes more complicated as the prophecy progresses towards the sixth.
Use with caution. (Heh!)
Ut in omnibus laudetur Dominus.
