What was one of the defining features of Renaissance musical style?

One of the defining features of Renaissance musical style is the use of polyphonic texture with imitative counterpoint. During the Renaissance, composers developed more complex musical structures, characterized by interweaving melodies that could stand independently while simultaneously creating harmony. This approach allowed voices or instruments to imitate each other, leading to rich, multilayered compositions.

Imitative counterpoint became a hallmark of the period, enabling composers to create works that were not only intricate but also expressive and beautifully harmonious. This shift towards polyphony marked a significant departure from the more homophonic textures that had dominated earlier periods and signified a deepening understanding of musical form and structure.

The other options present characteristics that do not align with the essence of Renaissance music. The emphasis on solo instrumental performances, while present, was not as defining as vocal polyphony in this period. Repetitive rhythmic patterns without harmonies and strictly monophonic textures were characteristics more commonly associated with earlier musical styles, such as Medieval music. Thus, the hallmark of Renaissance music lies prominently in its polyphonic and counterpoint techniques.
