The barline is a notational construct that identifies the hierarchical structure inherent in a sequence of beats. That hierarchical structure has strong perceptual and musical effects – the difference between the most mundane 3 4 | 1 pattern in Western music and the highlife timeline is entirely due to the impact of a perceived (but otherwise silent) barline. Computational modeling often represents beat patterns as strings of one-bit variables, indicating whether a given timepoint is articulated by a beat or not. While this representation has been productive both analytically and generatively, what might be gained by an explicit encoding of the barline? How could such a representation include and expand upon existing techniques for measurement of similarity, among other tasks? This paper reviews the analytical and generative consequences of explicitly hierarchical representations of rhythm.
