A '''word''', in mathematical terminology, is a sequence of letters from some finite alphabet, such as "aabaaab" or "LLsLLLs." In music theory, they are often used to represent an abstract scale template with some specified pattern of step sizes, such as when working with [[MOS]] scales.

For example, the word "aabaaab" can be thought of as representing a '''scale template''' where "a" represents one kind of step, and "b" represents a different kind of step. It is often useful to specify the relative sizes of the steps as well, leading to the two related words "LLsLLLs" and "ssLsssL," where L means "large" and s means "small." Of these, LLsLLLs basically corresponds to the diatonic scale, and ssLsssL the anti-diatonic scale; aabaaab can be thought of a more generic word incorporating both into a single template.
