Neume - Rhythmic Interpretation

Rhythmic Interpretation

The Solesmes monks also determined, based on their research, performance practice for Gregorian chant. Because of the ambiguity of medieval musical notation, the question of rhythm in Gregorian chant is contested by scholars. Some neumes, such as the pressus, do indicate the lengthening of notes. Common modern practice, following the Solesmes interpretation, is to perform Gregorian chant with no beat or regular metric accent, in which time is free, allowing the text to determine the accent and the melodic contour to determine phrasing. By the 13th century, with the widespread use of square notation, it is believed that most chant was sung with each note getting approximately an equal value, although Jerome of Moravia cites exceptions in which certain notes, such as the final notes of a chant, are lengthened. The Solesmes school, represented by Dom Pothier and Dom Mocquereau, supports a rhythm of equal values per note, allowing for lengthening and shortening of note values for musical purposes. A second school of thought, including Wagner, Jammers, and Lipphardt, supports different rhythmic realizations of chant by imposing musical meter on the chant in various ways. Musicologist Gustave Reese said that the second group, called mensuralists, "have an impressive amount of historical evidence on their side," (Music in the Middle Ages, p. 146), but the equal-note Solesmes interpretation has permeated the musical world, apparently due to its ease of learning and resonance with modern musical taste.
