Quote:

Gjerdingen's book Child Composers in the Old Conservatories made a lot of readers aware that valuable skills of music analysis, invention, and performance were not transmitted into the 20th and 21st centuries and the numerical functional chord analysis commonly taught is not the only way to conceive of and hear harmony. The Partimento approaches to music have been laid out in textbooks by Job Ijzerran (Harmony, Counterpoint, Portimento) and Giorgio Sanguinetti (The Art of Portimento).

Composers since Mahler, Berg, Stravinsky, etc. have generally expected performers to adhere to "what is on the page" and not stray into personal reveries
of improvisation. Stravinsky seems to have wanted Cahuzac to avoid all non-notated rubato and ornamentation, and certainly not substitute his own rhythms for the written ones or indulge in added improvised passages.
