The texture of Gregorian chant is said to be

a. monophonic.

b. homophonic.

The correct answer is A. Gregorian chant is monophonic which means that it has a basic texture. It consists only of melody and is not accompanied by a harmony. The same note is produced from men and women and all notes are sung together. The Gregorian chant is commonly used in churches and other religious congregations and was first developed in 9th and 10th century in western and central Europe. Pope St. Gregory the Great is credited for the chant.
