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).
Overview, including some physiological parameters, of the human circadian rhythm ("biological clock"). Chronobiology is a field of biology that examines timing processes, including periodic (cyclic) phenomena in living organisms, such as their adaptation to solar- and lunar-related rhythms. [1] These cycles are known as biological rhythms.
The numbers from +100% (maximum) to -100% (minimum) indicate where on each cycle the rhythms are on a particular day. In general, a rhythm at 0% is crossing the midpoint and is thought to have no real impact on one's life, whereas a rhythm at +100% (at the peak of that cycle) would give one an edge in that area, and a rhythm at -100% (at the ...
Polyrhythm: Triplets over duplets in all four beats [1] 2:3 polyrhythm (cross rhythm) as bounce inside oval Polyrhythm (/ ˈ p ɒ l i r ɪ ð əm /) is the simultaneous use of two or more rhythms that are not readily perceived as deriving from one another, or as simple manifestations of the same meter.

Rhythm is marked by the regulated succession of opposite elements: the dynamics of the strong and weak beat, the played beat and the inaudible but implied rest beat, or the long and short note. As well as perceiving rhythm humans must be able to anticipate it. This depends on repetition of a pattern that is short enough to memorize.
The neuroscience of rhythm refers to the various forms of rhythm generated by the central nervous system (CNS). Nerve cells, also known as neurons in the human brain are capable of firing in specific patterns which cause oscillations .
Human alpha rhythm has strong generators [clarification needed] in parieto-occipital areas [12] [13] which can be coherent with sources in the pulvinar and lateral geniculate nucleus. [14] They are generated in other neocortical areas as well. Oscillations in the alpha band called a mu wave can be found over the primary motor cortex. [15]
In music, syncopation is a variety of rhythms played together to make a piece of music, making part or all of a tune or piece of music off-beat.More simply, syncopation is "a disturbance or interruption of the regular flow of rhythm": a "placement of rhythmic stresses or accents where they wouldn't normally occur".
