Metric levels: beat level shown in middle with division levels above and multiple levels below. In music and music theory, the beat is the basic unit of time, the pulse (regularly repeating event), of the mensural level [1] (or beat level). [2]
A metronome (from Ancient Greek μέτρον (métron) 'measure' and νόμος (nómos) 'law') is a device that produces an audible click or other sound at a uniform interval that can be set by the user, typically in beats per minute (BPM). Metronomes may also include synchronized visual motion, such as a swinging pendulum or a blinking light.
For example, a tempo of 60 beats per minute signifies one beat per second, while a tempo of 120 beats per minute is twice as rapid, signifying two beats every second. The note value of a beat will typically be that indicated by the denominator of the time signature. For instance, in 4 4 time, the beat will be a crotchet, or quarter note.
Simplest form of metric modulation, unmarked (= ), in a piece by J.S. Bach. Slow introduction followed by an allegro traditionally taken at double the speed.Sixteenth notes in the old tempo prepare for eighth notes in the new tempo. [1]
The tapping rate is a psychological test given to assess the integrity of the neuromuscular system and examine motor control.The finger tapping test has the advantage of being a relatively pure neurologically driven motor task because the inertial and intersegmental interactions are so small that biomechanical influences on movement are reduced.

Metrical rhythm, measured rhythm, and free rhythm are general classes of rhythm and may be distinguished in all aspects of temporality: [14] Metrical rhythm , by far the most common class in Western music, is where each time value is a multiple or fraction of a fixed unit (beat, see paragraph below), and normal accents reoccur regularly ...
Music for step aerobics should be medium tempo, typically 118 to 122 beats per minute (bpm). A rhythm of 126–128 bpm is sometimes used for advanced classes; Reebok defined 128 bpm as the "fastest permissible speed." [41] The style of music should emphasize the beat, for instance a steady four on the floor rather than offbeat syncopation ...
