function [pitch, octave] = findpitch(freq)
%%%% Function takes in a frequency and returns the musical pitch of the frequency 
%%%% and its octave relative to the octave above middle C. 

%%%% Notes of the musical scale are assigned the following numerical values:
%%%% C  = 1
%%%% C# = 2
%%%% D  = 3
%%%% D# = 4
%%%% E  = 5
%%%% F  = 6
%%%% F# = 7
%%%% G  = 8
%%%% G# = 9
%%%% A  = 10
%%%% A# = 11
%%%% B  = 12

%%%% Octaves relative to the 12 notes of the "middle-C octave" are assigned a number 
%%%% corresponding to the number of octaves above or below the middle-C octave.  
%%%% For example a B two octaves above the B in the middle-C octave is assigned (12, 2),
%%%% while a B two octaves below the middle-C octave is assigned (12, -2).
octave = helpfindoctave(freq, 0);
pitch = choosepitch(freq/2^octave);
