Les tons, ou discours, sur les modes de musique, et les tons de l'Eglise, et la distinction entre iceux, de Pierre Maillart valencenois, chantre et chanoine de l'eglise cathedrale de Tournay : divisez en deux parties : ausquelles a esté adjoustée la troisiesme, par ledict autheur, en laquelle se traicte des premiers elements & fondements de la musique.
A 1610 Tournai treatise on church modes and tones by Pierre Maillart, a singer and canon of the cathedral at Tournai, printed by Charles Martin for church musicians and students of plainchant. Its pages mix dense typeset text with tables of hexachord and tetrachord syllables, short staff-lined chant excerpts with square notes, and a printer's device of a dove within an oval; a designer could take the rigid grid of letterspaced labels, the bracketed diagrams, and the small woodcut emblem as models for structured, scholarly layouts.
