This work, the first in the Libro segundo, is an intabulation of a motet setting by Francesco de Layolle of the Vespers psalm “Laudate Dominum” (Ps 116).. Valderrábano’s rubric indicates “The C clef is located on the the third course on the first fret, meaning that the first red cipher is an A.” The secunda pars of the moter is the doxology. This version is apparently the unique source of this setting and does not correspond to the setting indicated by Brown (BrownI, 100), Firenze: Biblioteca Nazionale Centrale: I-Fn Ms Magl. XIC, 117, nº33 (gil2017, 372). On the basis of the cadences and the tenor range, the work appears to conform to mode 2 more than mode 1.
