Pitch correlates with frequency but is also slightly level-dependent

Evidence

With complex tones, the effect is less well defined; Rossing (2001) suggests around 17 cents (0.17 of a semitone) for an intensity change between 65 dBSPL and 95 dBSPL. Rossing gives two suggestions as to where this effect could have musical consequences: (i) he cites Parkin (1974) to note that this pitch shift phenomenon is apparent when listening in a highly reverberant building to the release of a final loud organ chord that appears to sharpen as the sound level diminishes, and (ii) he suggests that the pitch shift observed for sounds with varying rates of waveform amplitude change, while f0 is kept constant, should be “taken into account when dealing with percussion instruments.” — David M.
