'''Alternating generator (AG) property''': A scale satisfies the alternating generator property if it satisfies the following equivalent properties: | |||
* the scale can be built by stacking alternating generators, for example 7/6 and 8/7. | |||
* the scale is generated by two chains of generators separated by a fixed interval; either both chains are of size m, or one chain has size m and the second has size m-1. | |||
'''[[constant_structure|Constant structure]]:''' A scale has constant structure (CS) if all Intervals of the same size are also within the same generic interval class. A single interval cannot be a part of two classes. The 12-tone diatonic scale does not have this property, since tritones can either be augmented fourths or diminished fifths. This is referred to as the ''partitioning property'' in most academic literature. | '''[[constant_structure|Constant structure]]:''' A scale has constant structure (CS) if all Intervals of the same size are also within the same generic interval class.
