Apparently this sheet music for the Good Friday Passion (according to St. John) chant notation is extremely rare.
These worn out, 3rd or 4th generation photocopies from 20 years ago are still much needed and in-demand.

Am I missing a cleaner version of this somewhere on the Internet? Does someone out there know how to use AI or some other software/filter to clean these up, so I can "renew" them? I'd like to make them cleaner, more like their original state.

CCWatershed doesn't have this, at least the last time I looked. They have just about everything else!

Any young people out there, any AI prompt geniuses want to try to clean these up?
I'm getting into AI myself, but mostly the text side for now (that's what my job involves). I'm still pretty new to the various image generators and what not.

I took 20 pictures with my phone, and they turned out about as good as the photocopies I have. But I'd really like to clean them up, if possible.

Even if they never get cleaned up, I'd like to provide these to the world, since they seem to be quite useful.

That is perfect!

The ONLY criticism is that there are 19 more pages.

But yes, Page 302 is absolutely done. If anyone wants to do more page(s) in Gimp, Photoshop, AI, or any other tool, please start on Page 303 and following.

It would be great to have at least some of them done by Weds. night. On Thursday morning I'll be travelling to a resistance chapel for Holy Week. So I'll print them all out, fixed or unfixed, the night before.

The Dominican priest (from Avrille) offering the Holy Week liturgy this year will no doubt appreciate it.

I used photoshop.  After set up it took 5 minutes.  I didn't know there were more till after I posted it.
I should have left the page number on, or do you want to renumber them?

Do you want the pencil notations left or removed so choir masters can make their own?

OK Clean copies and numbered.

Thank you Philip  Saves a lot of clean up work.  Great job!

You are most welcome Miseremini.  I found a hard copy of that same edition many years ago, almost unused, in a second-hand book shop and paid something silly like £1 for it.

Wouldn't it all be located in this book?

No, that appears to be a reprint of the 'Ordo Hebdomadae Sanctae Instauratus' that was first published in 1956 to replace the texts in the Missal and Breviary for Holy Week.  It has the new, shorter, texts of the Passion according to SS Matthew, Mark & Luke and the Passion of St John but not chant notation for them.  The Missal did not have that either and it was found in the Cantus Passionis a set of three books for the 'Deacons of the Passion', or in printed choir reference books as in the subject of this thread.
