Guitar-string inharmonicity creates audible beats on low strings.

Evidence

In particular for the lower strings of the guitar (E2, A2) the inharmonic spectra produce audible beats. From the digitally synthesized material, six short melodies were composed and presented to subjects in pairs. The subjects had to answer the question whether they prefer the first or the second realisation of a melody within a pair. — Professor Dr.-Ing. Hugo Fastl, Professor Dr.-Ing.
