quarturn

Quarturn is a term that can refer to several distinct concepts depending on the context. In the realm of music, a quarturn is a type of musical rest that lasts for a quarter of a whole note's duration. This is equivalent to a quarter rest. In some older musical notations, the term might have been used, though "quarter rest" is the standard modern terminology.

The word can also appear in informal or colloquial speech, often related to time. For example, someone might say they'll be back in "a quarturn," implying a short period of time, perhaps a quarter of an hour or simply a brief interval. This usage is not standardized and relies on the listener's understanding of the speaker's intent.

In the context of engineering or mechanics, a "quarturn" might describe a quarter turn of a valve or a similar component, signifying a 90-degree rotation. This is often used for simple on/off mechanisms. The specific meaning is always derived from the surrounding discussion or the object being described. Without further context, "quarturn" is an ambiguous term.
