* In mathematics, a function whose output contains values that repeat periodically is called a periodic function.
* In chemistry, the periodic table is a table which classifies the chemical elements by means of the periodicity of their chemical properties.
* In physics, period is the number of cycles as a result of time (time/cycle). The amount of time it takes to complete one full revolution. Period is also the inverse of frequency.
* In music theory, periodicity is described as "predictability gives rise to expectations".
