Improvisation was a basic skill practiced by every choirboy during the Renaissance. [...] Improvised polyphony was everywhere in the Renaissance. [...] Canguilhem (2011, 99) estimates that “the vast majority” of the polyphony heard in Philip II’s chapel in sixteenth-century Spain was improvised. In earlier centuries the amount might have been even higher. The composed polyphony that comes down to us was a small fraction of the musical landscape. This realization transforms our sense of the past.”
