Answer:
False
Step-by-step explanation:
Gregorian chants were often sung by male choirs and the music is still used for worship today. Like the music in previous time periods, medieval music was often based on modes. Modes were used before the modern day scales that we are more familiar with. They were "a series of pitches in predefined order, with specific intervals between each pitch." Seven different modes were used to compose and play music: Ionian, Dorian, Phrygian, Lydian, Mixolydian, Aeolian, and Locrian. Each of these modes starts on a different note and continues on the major scale. For example, the Dorian mode begins on D and moves upward from there (so the mode would be D, E, F, G, A, B, C, D). Likewise, the Phrygian mode begins on E and moves up the major scale to also end in E. Gregorian chants used these simple modes.
