Dvo dialoghi della mvsica del Signor Lvigi Dentice, gentil'hvomo Napolitano ; delli quali l'uno tratta della theorica, & l'altro della pratica: raccolti da diuersi autori greci, & latini
Luigi Dentice's 1553 Italian treatise on music theory, printed in Rome by Vincenzo Luchino, gathers Greek and Latin sources into two dialogues on theory and practice. Its pages show diagrams of modal scales: rows of tiny stacked ovals joined by brackets and labelled with Greek tone names, numbers and letter pitches, drawn in plain black ink with a clean, schematic structure a designer could borrow for diagrammatic or timeline layouts.
