For most of history music lived only in memory: you learned a song by hearing it. This lesson is about the moment that changed in Europe, in the churches of the early Middle Ages, and the tools that made it possible.
Gregorian chant
Gregorian chant is the central tradition of Western plainchant: sacred song in Latin, sung in one line without accompaniment. It developed mainly in western and central Europe in the 9th and 10th centuries. Legend credits Pope Gregory I with inventing it; scholars think he ordered a compilation of melodies rather than writing them. For centuries the chant was passed on orally.
Neumes: the shape of a melody
The first written signs for the chant, the neumes, were marks over the words that showed the general shape of a melody, up or down, but not its exact notes or rhythm. They reminded a singer of a tune already learned. Later, "heightened" neumes were placed higher or lower to show relative pitch, and then a four-line staff fixed particular pitches.
Guido of Arezzo
Guido of Arezzo, an Italian Benedictine monk born around 991–992 and active after 1033, is regarded as the inventor, or by some the developer, of modern staff notation. With it he could teach large amounts of music quickly. His treatise, the Micrologus, was the most widely distributed medieval book on music after Boethius. He also gave us the syllables ut, re, mi, fa, sol, la, from a Latin hymn: see Do re mi.
| Stage | What a singer could read |
|---|---|
| Oral tradition | Nothing: the tune is learned by ear |
| Early neumes | The rough shape of the melody |
| Heightened neumes | Which way and roughly how far it moves |
| Guido's staff | The exact pitch of every note |
Why it matters to a producer
Notation was the first technology that let music travel without the musician. Every later lesson in this course, from the printing press to the MP3, is another step in the same direction.
