This year at public Tenebræ in my parish, two of my schola members, to my surprise, said they didn't feel comfortable singing lessons - not lamentations, but the lessons in the 2nd and 3rd nocturn - on account of not having a score, but only the pointed text and a cheat sheet with the cadences.

I personally vastly prefer singing lessons from the text alone than from a fully notated score, but to each their own.

I am well aware of the 1934 Cantus Lamentationum, but it has only the lamentations as the text suggests - and it does not have the Roman tone found in the Liber Usualis and in the 1922 Holy Week ed.typ.

Is anyone aware of a book that would have both the Roman and Hispanic Lamentations, and full notation for the other lessons, in all three Lesson tones?

If it does not exist, I will self-publish it, it will be less than a day's work.

Searching this forum yields a few PDFs but no complete results. The closest seems to have been Hugh https://forum.musicasacra.com/forum/profile/170/Hugh with his publications on Fidelity Books, but they are no longer listed by Fidelity Books, plus his booklets only had one tone for each lesson.
