Rhythm

Rhythm is the most basic concept of music. In all cultures worldwide, the most simple and basic forms of music are purely rhythms. A rhythm is a pulse; a repetition of sounds in a pattern. Simple rhythms can be recognized straight away. Tapping rhythmically at a drum constitutes tapping it at timed intervals in a pattern. The most common rhythmic pattern in modern-day Western music is 4 / 4 time (say four-four time). This is where four pulses come one after the other, with the first of each four being given emphasis (known as an accent). Try this exercise:
Say the words "one, two, three, four, one, two, three, four..." etc. continuously, and at even time intervals.
Now each time you say "one", say it slightly louder: "one, two, three, four, one, two, three, four..." etc.
You have just been saying the words "one", "two", "three" and "four" in 4 / 4 time.

Rhythm (from Greek ῥυθμός – rhythmos, "any regular recurring motion, symmetry") may be generally defined as a "movement marked by the regulated succession of strong and weak elements, or of opposite or different conditions."  This general meaning of regular recurrence or pattern in time may be applied to a wide variety of cyclical natural phenomena having a periodicity or frequency of anything from microseconds to millions of years.

 In the performance arts rhythm is the timing of events on a human scale; of musical sounds and silences, of the steps of a dance, or the meter of spoken language and poetry. Rhythm may also refer to visual presentation, as "timed movement through space." and a common language of pattern unites rhythm with geometry. In recent years, rhythm and meter have become an important area of research among music scholars. Recent work in these areas includes books by Maury Yeston, Fred Lerdahl and Ray Jackendoff, Jonathan Kramer, Christopher Hasty,William Rothstein and Joel Lester.
