Notes on Meaning

• Primary vs. Musical Meaning: In contemporary English, "duple" is a specialized term. Its most frequent and recognized use is in the context of music theory to describe meter. Its general meaning ("consisting of two") is considered rare or technical.
• Distinction from "Double": "Duple" typically describes an inherent structure or division into two (like a meter). "Double" can describe that but also implies multiplication by two, repetition, or being twice as much.
