Semitone Interval Histogram


Refined Contour Histogram


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


Relative duration classes are based on the duration of the beat. Absolute duration classes are based on 120 bpm. See here for a definition of classes.
