THE power spectrum S(f), of many fluctuating physical variables, V(t), is ‘1/f-like’, varying as f−γ (0.5≲γ≲1.5), over many decades of frequency (see ref. 1 for review). We have found that loudness fluctuations in music and speech, and pitch (melody) fluctuations in music exhibit 1/f power spectra.
