Map

The word map could refer to:

• In regular temperament theory, a single row of a mapping, including a mapping with only one row (an ET map). "Map" is usually synonymous with "val", except that tuning maps and keyboard maps are not vals because they may contain non-integer entries.

• In mathematics generally, any function from one set to another. See Wikipedia

• In RTT, a linear form, which is a function that can be represented by a covector, and "mapping" has the more specific meaning given here: mapping. The shorter word refers to the simpler object.
