Palm Sunday has some really beautiful music.
It would be great to empower as many Catholics as possible to sing the Mass. Using the Gregorian chant Ordinaries - Kyrie, Gloria, Credo, Sanctus, Agnus Dei - and the Propers: Introit, Gradual, Alleluia/Tract, Offertory, Communion.
For Palm Sunday, I have two motets in mind - O Crux Ave by Fr David Friel or Popule Meus by Victoria. They’re both 4 parts, so we need some good singers to pull that off. If we can’t manage that complexity, we can sing other pieces - like Vexilla Regis or Ave Verum or maybe the regular chant reproaches.
