*chromatic-scale*

Holds a tuning of the standard chromatic scale. Note names in the chromatic scale are formed by combining a pitch class name from (c d e f g a b) with an optional natural (n), sharp (s), flat (f), double-sharp (ss) or double-flat (ff) and an optional octave number -1 to 9. For example, a4 is tuning A with a key number of 69, or 440 Hz; the note c-1 is the C in the lowest octave, or key number 0 at 8.175798 Hz and note bss9 is the highest note in the scale at key number of 133 with a frequency of 17739.684 Hz.
