When interpreting emotion and other qualities in music, performers seldom play exactly on every beat. In a musically expressive performance, the pulse generally does not align with the clicks of a metronome. [2] [3] This has led some musicians to criticize use of a metronome, because "musical time is replaced by clock time". [4]
On electric clocks such as quartz clocks, the music is usually generated using an electronic sound module. Most of these quartz musical clocks utilize either FM synthesis or sample-based synthesis technology for sound generation to produce high-fidelity and complex music, similar to the sound generation methods of electronic musical instruments.
A torsion pendulum clock, more commonly known as an anniversary clock or 400-day clock, is a mechanical clock which keeps time with a mechanism called a torsion pendulum. This is a weighted disk or wheel, often a decorative wheel with three or four chrome balls on ornate spokes, suspended by a thin wire or ribbon called a torsion spring (also ...
Quartz clocks and quartz watches are timepieces that use an electronic oscillator regulated by a quartz crystal to keep time. This crystal oscillator creates a signal with very precise frequency, so that quartz clocks and watches are at least an order of magnitude more accurate than mechanical clocks.
Research in music cognition has shown that time as a subjective structuring of events in music, differs from the concept of time in physics. [2] Listeners to music do not perceive rhythm on a continuous scale, but recognise rhythmic categories that function as a reference relative to which the deviations in timing can be appreciated.

Devices and methods for keeping time have gradually improved through a series of new inventions, starting with measuring time by continuous processes, such as the flow of liquid in water clocks, to mechanical clocks, and eventually repetitive, oscillatory processes, such as the swing of pendulums. Oscillating timekeepers are used in modern ...
The mechanism which runs a mechanical clock is called the movement. The movements of all mechanical pendulum clocks have these five parts: [27] A power source; either a weight on a cord or chain that turns a pulley or sprocket, or a mainspring. A gear train (wheel train) that steps up the speed of the power so that the pendulum can use it.
