>The perceived frequency of a sound or note. I think the claim that pitch is a partial function of loudness is about perception. If pitch is defined as the 'percieved' frequency, then it includes whatever synthesis of sensory data the brain uses. The most obvious, is a comparison to concurrent or recently heard sounds. A b-flat preceeded by a c really does sound different than one preceeded by a g. (At least, it really does for me). Edit: But my understanding of pitch has also, always been pitch = frequency.
