E HAVE ADDED rehearsal videos for the first section of a Palestrina Mass—section 1 of 3. Soon, we will add the missing sections. You can find it as #81668 at the Lalemant Polyphonic tome. Naming the files is always difficult. Palestrina based the Mass upon what we now refer to as “Mass II”—but the Masses were not numbered the same way when Palestrina was alive as they are now. Perhaps the easiest and most accurate name would be Kyrie Fons Bonitatis. Giovanni Pierluigi da Palestrina called the Mass: IN MAJORIBUS DUPLICIBUS.
This little piece is harder than it looks, by the way—so be on your guard!
