Manuscript originally from the James de/von Rothschild collection, current whereabouts unknown. The original MS appears to have songs, tablature for 4 course diatonic cittern, and lyric poetry and songs without music (the copy I have contains only the tablature portions). Among the cittern pieces, the majority are dance types with a few texted pieces (presumably meant to be sung) and a few (untexted) chansons. The MS also contains two works which could be played as duets on citterns a 5th apart, and a third piece (bassus) which may have been intended to be a duet as well, though no accompanying part survives.

Many of the pages include incipits of Latin phrases. These have not been included in the notes below. "Picot #" refers to the cataloguing originally done by E. Picot in Catalogue des livres composant la bibliotheque de feu M. le baron James de Rothschild, Paris, 1884(?) or 1912(?).
