Rhythm may also refer to visual presentation, as "timed movement through space" [5] and a common language of pattern unites rhythm with geometry. 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.
A circadian rhythm (/ s ər ˈ k eɪ d i ə n /), or circadian cycle, is a natural oscillation that repeats roughly every 24 hours. Circadian rhythms can refer to any process that originates within an organism (i.e., endogenous ) and responds to the environment (is entrained by the environment).
Examples include circannual or annual cycles that govern migration or reproduction cycles in many plants and animals, or the human menstrual cycle. Ultradian rhythms , which are cycles shorter than 24 hours, such as the 90-minute REM cycle , the 4-hour nasal cycle , or the 3-hour cycle of growth hormone production.
These rhythms are influenced by variable environmental cues, and in some species are influenced by internal cues. In a study conducted by Catalina Reyes, the authors took a further look into how red-eared sliders showed circadian and circannual rhythms in metabolism, and if metabolic rates overall influenced the circadian and circannual cues.
However, this appears to be the first harmonic of the circadian rhythm of each and not an endogenous rhythm with its own rhythm generator. Other ultradian rhythms include blood circulation, blinking, pulse, hormonal secretions such as growth hormone, [3] heart rate, thermoregulation, micturition, bowel activity, nostril dilation, appetite, and ...

J. S. Bach and George Handel used syncopated rhythms as an inherent part of their compositions. One of the best-known examples of syncopation in music from the Baroque era was the "Hornpipe" from Handel's Water Music (1733). "Hornpipe" from Water Music "Hornpipe" from Water Music. Christopher Hogwood (2005, p. 37) describes the Hornpipe as ...
For example, newly married or cohabiting couples often need to adjust to each other's sleeping rhythms when beginning to share the same bed for the first time. This adjustment can be difficult and may lead to disruptions in sleep quality and quantity, and possibly increase risk for depression as a result.
