A processed version of the four partial corpora of monophonic medieval chants and the associated analysis software by Max Haas. The project is from around 2014 and was accessible via http://www.oralhistoryofchant.ch/chantdigger until recently. I restored it with the [Web Archive] and created a mirror version here: https://chantdigger.web.app/ or now also again at https://oralhistoryofchant.ch/)

The repository serves to mirror the data compiled by Haas, to convert it into a modern format, and thus to preserve it for use in the research community.

Included are four sub-corpora, with the following editions serving as a guide:

• AntMed: Gregorio Maria Suñol (Hrsg.), Antiphonale missarum juxta ritum sanctae ecclesiae Mediolanensis, Rom 1935;
• GrTr: Graduale triplex seu Graduale Romanum Pauli PP. VI cura recognitum & rhythmicis signis a Solesmensibus Monachis ornatum, Neumis Laudunensibus (Cod. 239) et Sangallensibus (Codicum Sangallensis 359 et Einsidlensis 121) nunc auctum (1979);
• OffTr: Offertoriale triplex cum versiculis, [hrsg. v. Rupert Fischer], 1985;
• MM: Graduale Vat 5319, herausgegeben von Stäblein/Melnicki (Die Gesänge des altrömischen Graduale Vat. lat. 5319, Einführung von Bruno Stäblein; Notenteil, kritischer Bericht und Verzeichnisse von Margareta Landwehr-Melnicki, Kassel: Bärenreiter, 1970 [Monumenta monodica medii aevi II]).

The chants will be provided in a JSON format readable by the monodi+ edition software and in MEI. (In progress)

Code and data are free in the sense of open source: I ask to rename possible own products, so that the name ChantDigger remains.

ChantDigger is a program which brings together basic material for the analysis of plain chant. It's a tool for research but it doesn't give results which can replace research done by human beings.

There's a guided tour (pdf) in English which should give a fair basic understanding of the program and its aims. And there is a short summary (pdf) in german:
