Final answer:
From the 'Middle Ages / Renaissance Music Documentary', three interesting facts include the development of polyphony, the role of the Gutenberg press in music distribution, and the shift of musical influence from the Low Countries to Italy during the Renaissance.
Step-by-step explanation:
Three facts that interested me from the 'Middle Ages / Renaissance Music Documentary' are the evolution of polyphony, the influence of the printing press, and the shift in music centers from Northern Europe to Italy.
During the Middle Ages, polyphony was a significant development, with the music moving from monophonic Gregorian chants to complex, multi-voiced structures. This transition was marked by the increasing use of the interval of the third, which had previously been considered dissonant, and the move towards smoother vocal parts with a wider range and less crossing over.
The invention of the Gutenberg press had a profound impact on the distribution of music, making it accessible on a wide scale and leading to increased demand among the emerging bourgeois class. This enabled the dissemination of a variety of musical works, including chansons, motets, and masses, and contributed to the unification of polyphonic practices.
There was also a notable shift in the epicenters of musical activity during the Renaissance. While the Low Countries were initially prominent, with an extensive system of music education, by the sixteenth century, Italy emerged as the new center of musical innovation. Cities like Venice and Rome became hotbeds for musical creativity, with the birth of opera and the absorption of Northern musical influences.
