Each line represents one octave, starting With octave 0.  Middle C is 523Hz and
Middle A is 440 (middle A is what all other note calculations are besed on;
each note it the 12th root of 2 times the previous one.)  You should be able to
arrange the Array into two dimensions if you want to access it using an octave
and note #.
