I have the sheet music for the "chanted" setting you mention, Heath. But it is, in my estimation, a seriously flawed setting in many ways beyond the obvious style it emulates.
I'm considering whether I can alot time to setting the chaplet myself before 2 Easter as I don't want to use either of the two EWTN versions. For the record, I actually think the sacropop version is more effective than the faux-chant version.

Heath, I'm going to walk the wire of your question without a net, I don't have the score in front of me (or a frontal lobotomy!)
Items about the ETWN "Chant setting" that bother me:
*The antiphonal response "have mercy on us, and on the whole world..." that uses a repeating ascending minor third (at some portions in a higher than comfortable congregational tessitura) so syllabically forced on "MER..." and "US..." it deters me from even recognizing those phrases as even emulating the principles of good chant. It, to me, remniscent of a kind of Celtic affect.
*The use of the minor second interval for "Holy God" that to my ears suggests a clear tonality of a raised 7th scale degree to what otherwise would be the tonic of a "minor" mode; I believe it implies essentially a harmonic minor scale relationship (I don't know if there's a "dominant" scale degree 5 that bolsters my recollection) which then implies a minor triadic tonality. That just doesn't fly from what I got at Chant Intensive. Now, Heath, I could be completely wrong about that and those other 49 brains from SD and the forum are welcomed to dispute my "take" on whether this is a valid criticism.
However, I fully recognize that this chaplet setting and its composer are not required to be authentic or even evocative (as in "gregoriana.") It just sounds so ill-conceived at this point of the chaplet in particular, to me.
*The shifts in "tonal centers" seem artificial from section to section.
That's pretty much it from me. I'd gladly send you the information for obtaining the music if you're interested. But perhaps there's a "Ford" version out there that has not as yet received broadband attention. And like I say, I'm personally interested in setting the chaplet as well.

I second Charles opinion. I always thought it was an inferior setting. Don't care for it at all.

I could be wrong, but I believe the setting is adapted from Polish religious folk song and is not meant to be in the Gregorian idiom--even if the music shows some chant influence, as much Eastern (to my ears) as Western.

I have composed an accompaniment for this version of the Chaplet. Unfortunately, the melody is copyrighted. Maybe I should see about getting permission for my accompaniment version, then I can share it without consequence.

Yes, it sounds more like Russian chant (of some period!). And the "Eternal Father" part was a bit tricky. But I am pleased with my version when I hear it.

And not too low or the last part sounds like Russian basses.

I have just received a response about the copyright issue on the text/tune of the Chaplet. So long as I don't offer my work for sale, I am free to distribute it. I simply need to add the copyright text to each of my documents. I will do this over the next few days.

I basically have three files:
1 Text on one side, text with melody on the reverse.
2 As above, but with Tudor English for the Prayers (notably the Apostle's Creed and Our Father) for use in Anglican use parishes.
3 Organ accompaniment in a modal style suitable to either of the above.

Anyone interested in receiving these in PDF format can email me privately.

ninaeng: You may give these a shot. (Didactic mp3s available there as well.)

I found this once and made a transcription, (note I'm not looking to start a conversation on whether Medjugore is a true apparition) I would reccomend taking it a little faster than the recording.

Here's the EWTN http://mercysong.bigcartel.com/product/chaplet-of-divine-mercy-sheet-music


Here's another one I've found, click where it says get a free copy http://www.haapala.com/sufferingservant/pr_sum_divinemercy.cfm

Nobody knows if any apparitions are authentic, and our faith doesn't rest on any of them. I think the fact that Divine Mercy was a Polish apparition, believed in by a Polish pope, is what has caused it to be widespread. In any event, thank you Steve Collins for the accompaniment file.

As part of a girlscout silver award project, we got these really neat Divine Mercy Books (The Divine Mercy: Message and Devotion) and the book has lots of excerpts from St. Faustina's Diary. It's a really cool compilation, but no I haven't read the entire thing.

Here is my other file, in its latest version that includes the Copyright acknowledgement. As long as it's shared and not sold, it's free to use. I set it up to be printed on 8.5x11 card-stock and cut in half.

Happy Eastertide.

For me, it's not about the apparition, it's the message. Jesus' mercy plain and simple. The graces received from that day are huge!

So glad to find this thread!

MJ, Might I have a copy of your transcription? I'm curious if you use stems. My eyes go nuts reading all the eighth notes, otherwise I'd use Steve's admirable handout.

I don't really like this chant-like setting, I admit. The oddity of setting English to thoroughly eastern melodic fragments doesn't delight me a ton. But... we're starting to pray it with our boys and I want them to be able to plug into devotional life outside our family. The pop version, on paper, works a little better with the text. I can see where a comp prof would prefer it... but oh, the style is quite foreign to group singing. IMHO, it does not work well unless one is a Life Teen Diva singing in the shower.
