A 1643 Roman choral partbook by Domenico Massenzio, printed by Lodovico Grignani, containing vespers psalm settings for four voices to be sung by church choirs with organ. The page shows a decorated historiated initial letter at the left above staves of square-note chant, with a red-ruled staff, Latin text set under the notes, and a printed page number and voice label at the top. A designer might take the dense staff rhythm and the ornate capital as a model for structured, text-and-music page layouts.
