	A [[scale]] is said to have '''constant structure''' ('''CS''') if its ~~generic~~ interval ~~classes~~ are distinct. That is, each interval size that occurs always ~~spans~~ the same number of steps. This means that you never get something like an interval being counted as a fourth one place, and a fifth another place.		A [[scale]] is said to have '''constant structure''' ('''CS''') if its [[interval class]]es are distinct. That is, each [[interval size]] that occurs in the scale always [[subtend]]s the same number of steps. This means that you never get something like an interval being counted as a fourth one place, and a fifth another place.

	The term "constant structure" was coined by [[Erv Wilson]]. In academic music theory, constant structure is called the partitioning property, but Erv got there first.
