François-Pierre Goy has classified the signs which appear in the sources as follows:

Notation of the Basses
Precise observations of the ways the bass courses are notated can result in clues as to the source of a repertoire, or writer. This is especially true for early sources of the music in Accords Nouveaux.

Left-hand fingerings

Right-hand fingerings
This table contains much information on the playing technique used for the music of the Accords Nouveaux.

Ligatures

Ornaments

Diverse other signs

All these tables are part of the thesis and will be integrated into the Guide pratique.

The data bank of the signs and their occurrence in the sources is work in progress.
