Anyone involved in the production of music, at the least, should understand the basics of sound frequency and how it works. Every record you have heard or danced to is made up of a collection of sound frequencies. The music itself is just a collection of sound frequencies that sound good together. In this article, you will learn what a sound frequency is and how it works. You will also learn about the frequency spectrum, the frequency of sound waves, and how to train ears to identify certain sound frequencies. If you pluck a guitar string, tap a table, or sing a note, the object or instrument you are using vibrates, which then disturbs particles in the air. The disturbed air particles subsequently disturb the ones next to them, and the ones next to those, on so on. What you get is a domino effect of air particles bumping into each other hence the term frequency of the sound wave.

If you could see this happening around you, it would look something like this. To understand the basics of a sound frequency, all you need to understand is:

Sound is a collection of waveforms in the air that we perceive as sound.
Waveforms are the particles crashing into each other and separating, repeatedly.
The number of waveforms produced in a certain time frame – we use per second – is referred to as Frequency.
Note: Waveform and Frequency are often used interchangeably. Be aware of this.
