For that reason some people prefer to describe pitch in terms of musical scales. The unit of the scale is the octave, where an octave is a doubling of frequency. Each octave is broken into 1200 logarithmically equal steps called cents. This table shows the values of notes in the Western musical scale in cents and in frequency. Notice that the exact pitch of the notes is not generally agreed upon; there are different versions of the scale. That means that different people ÒhearÓ the steps in scale as being correctly spaced at different frequencies.
