-In mathematics generally, '''map''' is another word for '''mapping'''. In the [[RTT]] writings of [[Dave Keenan]] and [[Douglas Blumeyer]], their convention is for "map" to refer to a single-row [[mapping]].
+In mathematics generally, '''map''' is synonymous with "mapping" and "function". In RTT, both "map" and "mapping" have the more specific meaning of a [[Wikipedia:Linear_map|''linear'' map]], which is a function that can be represented by a matrix, but it is common to reserve the shorter word "map" for a single row of such a matrix, such as a [[tuning map]] or [[ET]] map. In this single-row sense, a map may also be viewed as a [[Wikipedia:Covector|covector]], and when unqualified, is synonymous with "[[val]]" (tuning maps are usually not vals because they usually have non-integer entries).
-A [[Val#Vals_vs._maps|val]] is a special type of mapping, but in almost all RTT cases, when using Dave and Douglas's convention, map and val are interchangeable.
