“Inaudible music may seem an odd notion, even a foolishly Romantic one—although it is partly the Romantic prejudice in favor of sensuous experience that makes it seem odd. Still, there are details of music which cannot be heard but only imagined, and even certain aspects of musical form which cannot be realized in sound even by the imagination.”

The Cool, Cool River
Song lyrics, The Rhythm of the Saints (1990)

H. E. Butler's translation:
Indeed nature itself seems to have given music as a boon to men to lighten the strain of labour: even the rower in the galleys is cheered to effort by song. Nor is this function of music confined to cases where the efforts of a number are given union by the sound of some sweet voice that sets the tune, but even solitary workers find solace at their toil in artless song.

De Institutione Oratoria (c. 95 AD)
Original: (la) Atque eam natura ipsa videtur ad tolerandos facilius labores velut muneri nobis dedisse, si quidem et remigem cantus hortatur; nec solum in iis operibus in quibus plurium conatus praeeunte aliqua iucunda voce conspirat, sed etiam singulorum fatigatio quamlibet se rudi modulatione solatur.
