Meaning of Difference Tone in Music
In music, the term "difference tone" refers to an additional tone that is perceived when two real tones are sounded simultaneously. It is a psychoacoustic phenomenon where the brain creates an artificial tone that is not physically present in the original sounds. The difference tone is heard as the mathematical difference between the frequencies of the two original tones.
The discovery of difference tones is credited to the violinist Giuseppe Tartini, who noticed the phenomenon while playing double stops on the violin. Difference tones can be heard when two tones are played close together in pitch, such as when playing harmonics or intervals on a musical instrument.
Difference tones are also known as "combination tones" or "resultant tones". They are perceived as a result of the interaction between the ear and the auditory system, and they contribute to the overall perception of sound in music.
It is important to note that difference tones are different from overtones, which are additional tones that are naturally produced by vibrating objects and are present in the harmonic series of a fundamental frequency.
Overall, difference tones add complexity and richness to the sound and can enhance the musical experience by creating new harmonies and textures.

A lower tone (pitch) that is heard when two higher notes (pitches) are performed in such a way that the frequency of the difference tone is the difference of the frequencies of the other two tones (notes). This effect is often noticeable when two clarinets are playing in thirds.
