When additional harmonics are added, the nature and tone of the sound alter. Generally, this adds depth, presence, or warmth to the sound, making it richer and more engaging.

Harmonics are classified into two categories: even and odd. Even harmonics are produced by multiplying the fundamental frequency by even numbers, whereas odd harmonics are produced by multiplying the fundamental frequency by odd numbers. For example, if your fundamental tone is a 1 kHz sine wave, an even harmonic is 2 kHz, and an odd harmonic is 3 kHz. Each set produces a distinct sound, which is essential for creating a captivating sound.
