Final answer:
The correct option is c) "Sacred".
The term that identifies music written for the church is 'Sacred'. This is in contrast to secular music, which is not associated with religious practices. Sacred music has been an integral part of worship throughout history.
Step-by-step explanation:
The word that identifies music written for the church is c) "Sacred". Unlike secular music, which encompasses forms such as the German Lied, Italian madrigal, and the French chanson, and is independent of the church, sacred music is specifically composed for religious ceremonies and services. During different periods of history such as the Medieval and Renaissance eras, sacred music played an integral role in worship and religious instruction. Despite the rich variety of secular music during these times, it is the sacred genre that is directly associated with the Church.
In the Medieval period, monophonic liturgical genres like Gregorian chant were used in religious settings. As time progressed, polyphonic forms emerged, strengthening the variety and complexity of sacred music. During the Renaissance, while secular genres like the madrigal gained popularity, it was sacred music that continued to dominate in religious contexts. Therefore, when referring to music written for church services, the appropriate term is sacred.
