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.
