This experimental project is centered on producing and making available: a) a full digitization of the notebooks containing texts that are included in Os Degraus do Parnaso (DP). These notebooks are known as «Musikästhetik», siglum M (Biblioteca Nacional de Portugal, Archive E62/205); «Harmonielehre | III | Skizzen», siglum H; and «Notizbuch | Ab | Sommersemester 1984», siglum N (the second and third items are at present in the hands of a private collector), b) a TEI/XML transcription of the notebooks focused on the DP texts; c) a codicological description of each notebook.
