Translation of the text: We introduce several tones consisting of the first five harmonics. The frequency of the fundamental (first harmonic) for all samples is f = 400 Hz. Successively the prominince of the different overtones is changed according to the corresponding spectra. Note that the pitch remains constant for all samples and that it corresponds to the pitch of the first harmonic (fundamental). As the order and prominence of the overtones increases, the tones will sound harsher.
