The harmonic series is also responsible for timbre: It is the reason one can hear the difference between a trumpet, violin, or flute, even if they play the exact same pitch: while the same set of frequencies is (mostly) present in all these sounds, some partials will be more prominent than others depending on the sound source: | The harmonic series is also responsible for timbre: It is the reason one can hear the difference between a trumpet, violin, or flute, even if they play the exact same pitch: while the same set of frequencies is (mostly) present in all these sounds, some partials will be more prominent than others depending on the sound source: | ||

In the video below, individual partials are gradually re-introduced to a recording of a vocalist singing on different vowels. A psychoacoustic illusion is created, where at a certain point, the sound of individual frequencies is suddenly interpreted by the brain as one, timbrally unique and recognizable sound: the human voice. Also, note how the intensity of each partial varies with different vowels. | In the video below, individual partials are gradually re-introduced to a recording of a vocalist singing on different vowels.
