Notes on Meaning

• The first meaning (capable of being measured) is the direct application of the word's Latin root (, from meaning "measure"). It is a more formal or technical synonym for "measurable."
• The second, specialized meaning (having notes of fixed rhythmic value) is primarily used in the historical context of music theory, specifically referring to the rhythmic systems of the late medieval and Renaissance periods (Ars Antiqua and Ars Nova). In this context, it contrasts with earlier unmetered or free-rhythm chant.
