The "perception" and "abstraction" of rhythmic measure is the foundation of human instinctive musical participation, as when we divide a series of identical clock-ticks into "tick-tock-tick-tock". Justin London writes that musical metre "involves our initial perception as well as subsequent anticipation of a series of beats that we abstract from the rhythm surface of the music as it unfolds in time". Yet other researchers suggest that since certain features of human music are widespread, it is "reasonable to suspect that beat-based rhythmic processing has ancient evolutionary roots". Other research suggests that it does not relate to the heartbeat directly, but rather the speed of emotional affect, which also influences heartbeat. In his television series How Music Works, Howard Goodall presents theories that human rhythm recalls the regularity with which we walk and the heartbeat. Percussion instruments have clearly defined sounds that aid the creation and perception of complex rhythms. Recent work in these areas includes books by Maury Yeston, Fred Lerdahl and Ray Jackendoff, Jonathan Kramer, Christopher Hasty, Godfried Toussaint, William Rothstein, Joel Lester, and Guerino Mazzola. In recent years, rhythm and meter have become an important area of research among music scholars. For example, architects often speak of the rhythm of a building, referring to patterns in the spacing of windows, columns, and other elements of the façade. Rhythm may also refer to visual presentation, as "timed movement through space" and a common language of pattern unites rhythm with geometry. In some performing arts, such as hip hop music, the rhythmic delivery of the lyrics is one of the most important elements of the style. In the performance arts, rhythm is the timing of events on a human scale of musical sounds and silences that occur over time, of the steps of a dance, or the meter of spoken language and poetry. A rhythmic group can be apprehended only when its elements are distinguished from one another, rhythm.always involves an interrelationship between a single, accented (strong) beat and either one or two unaccented (weak) beats. Rhythm may be defined as the way in which one or more unaccented beats are grouped in relation to an accented one. Rhythm is related to and distinguished from pulse, meter, and beats: This general meaning of regular recurrence or pattern in time can apply to a wide variety of cyclical natural phenomena having a periodicity or frequency of anything from microseconds to several seconds (as with the riff in a rock music song) to several minutes or hours, or, at the most extreme, even over many years. Rhythm (from Greek ῥυθμός, rhythmos, "any regular recurring motion, symmetry" ) generally means a " movement marked by the regulated succession of strong and weak elements, or of opposite or different conditions".
