A sound wave that has a frequency that is an integer multiple of a fundamental tone

Harmonics, also known as overtones, are a special sound effect in music that refers to the additional high-frequency tones generated simultaneously during the production of sound by an instrument or a sound generator.

When an instrument or sound generator produces sound, in addition to the main fundamental frequency, a series of higher frequencies known as harmonics are simultaneously generated. These harmonics exist at integer multiples of the fundamental frequency and form a harmonic series.

Harmonics possess unique timbre and resonance characteristics, enriching the sound quality of an instrument or a sound. In instrumental performance, musicians can generate and control harmonics through specific techniques and fingerings. In choral and vocal singing, singers can also produce harmonics by utilizing appropriate vocal techniques.

Harmonics have wide applications in music. They can be used to create unique sound effects, enhancing the richness and expressiveness of music. Harmonics are also commonly employed in experimental and innovative approaches in contemporary music, providing a sound experience distinct from traditional music.
