1. The Benedictine Option:
Father Samuel Weber, O.S.B., offers his complete English translation and music settings for the Propers of the Roman Missal,
see here for an introduction.
Complete, free, organ accompaniments are available at his website.
The hardcover book for Sundays and Solemnities is available for purchase here.
Choirs are posting audio of these for practice – COTT Choir, Slowman studio…
2. The Simple English Propers:
This provides complete entrance, offertory, and communion propers in English with psalms in modal chant, with four-line notation, for Sundays and solemnities. They can be sung by a single cantor or a full choir.
These are freely available in PDF here, with print books also available for purchase.
3. The Source and Summit
The author of the Simple English Propers went on to develop a full website, sourceandsummit.com, with facilities to select antiphons and propers for any Mass (English, Latin, and Spanish), and sheet music customizations to set any antiphon to any tone.
The website offers a basic playalong for selected antiphons and propers to help with rehearsal, with paid subscriptions.
However, Source and Summit Mass reading and Psalm texts are from the New American Bible, from the American Lectionary and Missal, not for Canadian dioceses.
