They embodied the basic rules of phonics into stories about these make-believe characters called Letter People.

For harmonic sounds, with this definition, it is therefore the harmonic partial that is augmented by a resonance. The difference between these two definitions reside in whether "formants" characterise the production mechanisms of a sound or the produced sound itself. In practice, the frequency of a spectral peak can differ from the associated resonance
