# Pitch, Pitch Interval, and Pitch Ratio Representation

To prevent confusion about pitch representation in general and pitch representation in Tarsos specifically I wrote a "document about pitch, pitch Interval, and pitch ratio representation":\[pitch_representation.pdf\]. The abstract goes as follows:

<blockquote>
This document describes how pitch can be represented using various units. More specifically it documents how a software program to analyse pitch in music, Tarsos, represents pitch. This document contains definitions of and remarks on different pitch and pitch interval representations. For good measure we need a definition of pitch, here the definition from \[McLeod 2009\] is used: *The pitch frequency is the frequency of a pure sine wave which has the same perceived sound as the sound of interest.* For remarks and examples of cases where the pitch frequency does not coincide with the fundamental frequency of the signal, also see \[McLeod 2009\] . In this text pitch, pitch interval and pitch ratio are briefly discussed.
