Downshifting all frequencies by a constant makes familiar music sound chime-like
Evidence
With this in mind, we have downshifted a segment of Chopin by 208 Hz; the sonogram in figure 26.18 confirms the shift. The sound files Chopin.wav and ChopinTransformed.wav available on whyyouhearwhatyouhear.com, differ by the 208 Hz downshift of the frequencies. Such a shift does not affect the playback rate. The tune is quite recognizable, and various chime-like and sour notes are heard. — Eric J. Heller, Why You Hear What You Hear- An…, 2419
