What does the prefix tempo mean?

The prefix "tempo" actually doesn't have a specific meaning on its own. It's derived from the Italian word "tempo," which means "time" and is used in music to refer to the speed or pace of a piece of music.

Therefore, "tempo" as a prefix is usually used to create words related to time or speed, such as:

* Tempometer: A device used to measure tempo.

* Tempo rubato: A musical technique where the tempo is slightly altered for expressive purposes.

* Tempo marking: A notation in music indicating the desired tempo.

However, it's important to note that "tempo" is not a common prefix in English, and most words related to time use other prefixes like "chron-" or "hor-" instead.
