I would choose option D. Renaissance music was polyphonic, lighter, and cheerful. Here's why:
1. During the Renaissance period (14th to 17th century), music became more polyphonic compared to the monophonic chants of the medieval era. This means that Renaissance music often had multiple independent melody lines playing simultaneously, creating rich harmonies.
2. Renaissance music was characterized by a lighter and more joyful tone compared to the solemnity of medieval music. Composers of the Renaissance period explored themes of love, nature, and human emotions, resulting in a more cheerful overall sound.
3. The use of instruments in addition to vocal music became more prominent during the Renaissance, further adding to the lighter and more varied musical texture of the time.
Overall, option D accurately captures the essence of Renaissance music, highlighting its polyphonic nature, light-heartedness, and cheerfulness as key characteristics of the musical style during that period.
