Pentecost VIII (also 14th Sunday of Ordinary Time) falls in July. The Communion for this Sunday is Gustate et videte/O taste and see. There are various settings, and my own setting is a 3-part canon, in various voicings (in both Latin and in English).

Note, this text can also be (and often is) sung at other times.

If you have a choir that learns music efficiently, I've spent some time editing polyphonic Propers for Time After Pentecost, which can be found under my contributor name on cpdl. Also, I've written a set for Sacred Heart.

Mass never quits, so neither should choir. But it's true that summer has personnel challenges, and your idea of repertoire that can be recycled over a month has merit.

Tom,

In the binders I inherited, we already have de la Rue's O Salutaris Hostia, but your edition is much easier to read. Thank you for reminding me of it.

About the Farrant, I know the original Lord, for thy Tender Mercies' sake. Do you know how it came to have a contrafactum (if that's the right word)? I'm fond of the original, but at a TLM I wouldn't use it, except possibly as a prelude or processional piece I guess, and I encountered the Latin version in December (it was sung at the Rorate Mass at the Cathedral in another diocese). I'm not sure if I think of the Latin edition as a sort of My Little Pony Gloria in reverse?

I have become a fan of Isaac, partly because of how closely connected his music is to the chant.

August has St. Philomena, the Assumption and our Patronal Feast, the Immaculate Heart of Mary.

I have a setting (SSA) of Diffusa est Gratia for St Philomena. Still thinking of other options for polyphony for all of those.

also for the Precious Blood - Ave Verum Corpus -
CPDL has a long list of compositions, in all kinds of arrangements.
happy hunting!!
