Sound basics overview

Prior to considering any of the sound-generating components found in a synthesizer, it’s important that you understand sound itself.

Technically, sound is the conversion of physical energy—such as a hand clap—to an air pressure disturbance. This change in air pressure is transmitted as a series of vibrations—a sound wave—through the air. Sound vibrations can also be transmitted through other matter, such as a wall or floor.

If the vibrations follow a periodic pattern, the sound is said to have a waveform.

The figure above shows an oscillogram—a graphical representation—of a sine wave, the simplest and purest kind of waveform.

If the vibrations do not follow a discernible pattern, the sound is called noise.

A repetition of a waveform—each peak and trough in the oscillogram—is known as a cycle. The number of cycles that occur per second determines the basic pitch of the waveform—commonly known as the frequency. Most instruments provide an oscillator frequency control, measured in hertz (Hz), that determines the number of cycles per second—and therefore the basic pitch of your sound.
