Final answer:
The false statement about the Renaissance madrigal is that it is always written in Latin, as madrigals often used the vernacular language.
Step-by-step explanation:
The statement about the Renaissance madrigal that is false is: The Renaissance madrigal is always written in Latin. Renaissance madrigals were indeed a popular form of secular vocal music that originated in Italy and are characterized by their polyphonic texture, which means they have multiple independent voice parts.
However, they were not restricted to the Latin language but were often written in the vernacular, which allowed for a wider expression of poetry and emotions, reflecting the spirit of the Renaissance.
