👉 Lacunars are a type of musical structure or pattern found in many languages and cultures, often used to represent musical notes or chords. These patterns can be made up of a series of repeating elements that can either be open-ended or closed-ended (i.e., they cannot be continued indefinitely). The term "lacunar" comes from the Latin word "laca," which means "to cut." Therefore, lacunars are often used in music to create an interesting and dynamic effect.
