Josquin based this gorgeous mass on Pange lingua gloriosi, a plainchant hymn in the Phrygian mode. Each polyphonic entrance in the mass is based on a phrase of the chant. This is a “paraphrase mass” - one of three approaches Josquin used as he composed masses. As he often did, Josquin here writes for alternating pairs of voices prior to bringing in all voices together as a kind of climax. This is one of 18 masses composed by Josquin and is one of the best known.
The tactus is the whole note, and I have suggested the tempo of 72 at which the accompanying recording was made. In the recording, a preparatory measure is provided on a wood block. The first voice to enter is part 3 Tenor.
There are many editions of this mass and some incorporate large amounts of musica ficta. I have used it sparingly. The text underlay is my own; in the days before bar lines, the location of syllables in the original manuscript is purely a matter of editorial conjecture.
Feel free to print the score and parts and also to perform the music.
