Answer:
During the Renaissance, the music had less theological themes than Medieval music, and the Renaissance was more polyphonic than the Medieval Era, which was mostly monophonic.
The printing press allowed chorales to be published, increasing their popularity. It also allowed for written music to be easier to read/access and more easily distributed.
Music in the Renaissance became more complex and less religious, which would be mirrored by the Enlightenment more than a century later.
Music was an essential part of civic, religious, and courtly life in the Renaissance. While the music was becoming less religious, the most important music of the early Renaissance was composed for use by the church, with polyphonic masses and motets in Latin for important churches and court chapels.
Composers, similar to remixes today, were able to use previously heard melodies, scales, and ostonados in order to create certain emotions in the listener by association. Reusing riffs made composing easier, as one didn't have to spend countless hours trying out different patterns, and could instead copy a melody completely, or shift it into a different key.
