In this section, we investigate some basic principles of auditory perception. First we examine the notion of pitch: how do we measure "high" and "low"; what is the nature of the correlation between physically measurable aspects of a tone's frequency and its perceived "height?" Next, we move on to a discussion of tones in an effort to differentiate the "height" of a tone from its "chroma." Finally, we discuss tonal paradoxes in which the standard separation of "height" and "chroma" is called into question.
