NL-Avu xv 00102 (cat.nr. 46)

Venite Exultemus, for each day of the week; Latin chants and Dutch rubrics. According to the catalogue is dates ca 1450-1500, but I think it is a century younger. Square notation on black staves. Only the psalm, fully written out with music, no invitatory antiphon, but the repetitions of the antiphon are inserted between the psalm verses (alternatim the entire antiphon and the second half).
