Gregorian Chant: The Eternal Song
By Cantor
The Mood of the Mode
One of the beauties of chant is that it teaches through sound. It is difficult for most of us to realize, without considerable effort, what life would be like if we could not read — it seems unimaginable. Yet, in the centuries when many of our most ancient chants were newly composed, only the educated minority could read. So, in an effort to teach the chant, composers often united certain sounds with certain texts or seasons. In this way, through repetition, people started to learn things such as the seasons of the church year, feast days, etc., through association with sound.
However, these composers did not just wake up one morning, get out their “catalog of modes” and say, “today, I shall compose in Mode II.” The definition and categorization of modes actually came after the chant already existed. It was a subtle skill they employed which was based upon a sense of using particular sounds to evoke or underscore certain emotions, thoughts, or ideas.
The image below is actually a chart with simple, modal descriptions of some of the great music theorists and composers of the last 1000 years: Guido d’ Arezzo (11th century), Adam de Fulda, (15th Century) and Juan Espinoza (17th Century). If you look at these descriptions and then take a look at some of your favorite chants, you might find you have a fresh perspective of some pieces that you know quite well!
