A scale satisfies the '''generator-offset property''' (also '''alternating generator''' or '''AG''') if it satisfies the following equivalent properties: | A ([[periodic scale|periodic]]) scale satisfies the '''generator-offset property''' (also '''alternating generator''' or '''AG''') if it satisfies the following equivalent properties: | ||
