IPA: /nɒnˈmɛtrɪkəl/
KK: /nɑːˈmɛtrɪkəl/
Describing something that does not follow a regular rhythm or meter, often used in music or poetry.
The composer created a nonmetrical piece that allowed for more expressive freedom.
Nonmetrical → It is formed from "non-" (meaning not) and "metrical" (from Greek "metron", meaning measure). The word "nonmetrical" means not related to or not based on a specific measurement or metric.
Think of 'not' ('non-') related to 'measure' ('metron') — that's why nonmetrical means not based on a specific measurement.
