Formants

– Formants are Resonances that Happen in the “Vocal Tract”

– Voices have a Distinctive Character which is Defined by Harmonics and its Formants 

– the Formants Essentially Define the Character of a Particular Voice / Sound (e.g. Woman, Child, Man etc.)

– a “Ah” Sung in the Pitch of C Does Not Sound Like “Eh” in the same Pitch

– Instruments have a Distinctive Character which is Defined by Harmonics and Formants

– Formants are Pretty Much Static in Spectrum, i.e. you can Change them Directly with an Equaliser (whereas Harmonics Follow the Pitch Constantly)

– Real World Formant Change Depends on Air / Vibration / Waves

– Formants are also Represented in the Harmonic Overtone Series by the Fact that every Key Correlates to another Key on the Piano (why Formants May be Used in Synths as well)

– sometimes Called “Timbre” (Tonal Shift)
