Music-Note-Frequency

There aren't any special instructions for installing the module, except
that it requires Music::Note from here: http://search.cpan.org/dist/Music-Note.

This module extends Music::Note to provide frequency values in Hertz (Hz) for
the note defined by the Music::Note object.  Frequencies are currently only
available for equal-temperament.  The formula used to generate the frequency
values from the MIDI pitch values is:

        f(n) = 2**((n-69)/12) * 440 Hz

This is a table of generated values listed with MIDI pitch values and note
names, just because:
