Electronic
music is a term for music created using electronic devices.
As defined by the IEEE standards body, electronic devices
are low-power systems and use components such as transistors
and integrated circuits. Working from this definition, distinction
can be made between instruments that produce sound through
electromechanical means as opposed to instruments that produce
sound using electronic components. Examples of an electromechanical
instrument are the teleharmonium, Hammond B3, and the electric
guitar, whereas examples of an electronic instrument are
a Theremin, synthesizer, and a computer.
Music is an art form that involves organized sounds and
silence. It is expressed in terms of pitch (which includes
melody and harmony), rhythm (which includes tempo and meter),
and the quality of sound (which includes timbre, articulation,
dynamics, and texture). Music may also involve generative
forms in time through the construction of patterns and combinations
of natural stimuli, principally sound. Music may be used
for artistic or aesthetic, communicative, entertainment,
ceremonial or religious purposes.
