Final answer:
Gregorian chant is not secular music but is instead sacred music used in the Roman Catholic liturgy, making the statement false.
Step-by-step explanation:
Gregorian chant is not secular music; this statement is false. Gregorian chant is a form of sacred music that was developed for use in the Roman Catholic liturgy. Throughout the medieval period, secular music became increasingly popular alongside sacred music. However, Gregorian chant remained purely religious, monophonic in style, and was used to enhance spiritual contemplation during services. In contrast, secular music during the Renaissance, which included genres like the madrigal and the chanson, was independent of the church and often had non-religious themes.
