My view: this could get tedious (after all, there are 53 Hail Marys in a set of mysteries!) Im wondering if perhaps you could adapt what some hispanic communities do when they sing a verse of a hymn after each mystery is introduced, but sing an appropriate chant instead (Marian or relating to the mystery being prayed.)

I would also agree that the rosary itself is probably better not sung. One could certainly precede or follow it with a chant, but in my opinion it is best to leave the rosary itself as a spoken prayer, in normal order, in either all English or all Latin.

However in Cantus Selecti (and I know this is in Latin), starting on page 142* there are chants for the rosary, including an antiphon for each mystery, and a hymn for each set of five decades. I suppose if you really wanted some English chants you could see about translating those.

Cantus Selecti is available on the Musica Sacra resource page, and hopefully this link also works: https://media.churchmusicassociation.org/books/cantus_selecti.pdf

@Sarah, In the Catholic Church Hymnal compiled by A. Edmonds Tozer's, there are hymns dedicated to the Most Holy Rosary. These are not chants but hymns for the Sorrowful, Joyful, and Glorious Mysteries and a few that are generally about the Rosary and its power over evil.

If this peeks your interest then I would be happy to scan them for you. Just send me a PM.

In our Monastery, We typically would chant the Hail Marys "Directum" on one note, ending with a flex between the leader and response. For the Our Father, one of the chant tones, Begin Each decade with a Antiphon that matches the mystery (as in Cantus Mariales), and Sing the Glory be according to that tone. O My Jesus "directum" . Hail Holy Queen (Salve Regina at the end). I have been working on making a document, but it wont be ready in time for the feast. When its finished I can post it.

Thank you to all who have answered! It was been a fruitful discernment process for me. I'm leaning on the "do it" side, but am open to re-evaluation in the future. I'll jump on an let you know how it goes.

I was able to contact Aristotle and he sent me his booklet. I will try to post mine soon.

Update: The sung rosary was lovely. I was very uncertain how it would go. I found it lovely to sing as did the four other ladies who joined me. Our pastor liked it a lot and the feed back so far from parishioners is overwhelmingly positive even from people I wouldn't have expected. I'm sure there's a few who weren't a fan but are nice enough to volunteer that to me.

The purpose was to singing it for the feast of Our Lady of the Rosary but, I've gotten some requests for us to do it each first Friday--- still need to think about that one.

If anyone is interested, here is the singer's guide and also congregation guide that we did. I pitched the first two psalm tones beginning on C, but nobody joined the third when the highest pitch was A (when our pastor felt comfortable singing), so I intentionally transposed the 4th and 5th decade lower than as written.
