sonitum et discrimina ad symphonias musicas sive concentus componuntur divisa in circinatione diatessaron et diapente et disdiapason, uti vox scaenici sonitus conveniens in dispositionibus tactu cum offenderit, aucta cum incremento clarior et suavior ad spectatorum perveniat aures.
The differences of the sounds which arise are combined into musical symphonies or concords: the circle of seats being divided into fourths and fifths and the octave. Hence, if the delivery of the actor from the stage is adapted to these contrivances, when it reaches them, it becomes fuller, and reaches the audience with a richer and sweeter note.
