Also known as “fuzzy intervals” or interval classification. See here for definition of classes

Metrical Circle Map (N=48) Histogram

Metrical circle maps divides the bar duration into equal sized bins (48 in this case) and maps metrical positions to the corresponding bin. (Labels normalized to 4/4 measure).

Duration Class (Abs. and Rel.) Histogram
