Electronic musical instruments

  • An electronic musical instrument is a musical instrument that produces its sounds using electronics. 

  • Some of them may include a user interface for controlling its sound, often by adjusting the pitch, frequency, or duration of each note.

  • However, it is increasingly common to separate user interface and sound-generating functions into a music controller (input device) and a music synthesizer.

  • Electronic musical instruments are now widely used in most styles of music. 

Electric guitar

  • An electric guitar is a guitar that uses a pickup to convert the vibration of its strings into electrical impulses.

  • The most common guitar pickup uses the principle of direct electromagnetic induction.

  • Since the output of an electric guitar is an electric signal, the signal may easily be altered using electronic circuits to add "color" to the sound.

  • Often the signal is modified using effects such as reverb and distortion.

  • It was invented in 1931, during the jazz era.

  • During the 1950s and 1960s, the electric guitar became the most important instrument in pop music.
