%Actual note frequencies can be found at %http://www.seventhstring.com/resources/notefrequencies.html
%Defining some possible note frequencies (in Hz). %Values/equations were either given or interpreted %from Table 1 in the problem.
%Middle Notes (Calculated from Table 1) A_Middle = 440; %Given in the problem C_Middle = A_Middle * (3/5); B_Middle = C_Middle * (15/8); G_Middle = C_Middle * (3/2); F_Middle = C_Middle * (4/3); E_Middle = C_Middle * (5/4); D_Middle = C_Middle * (9/8);
%Lower Notes (Half the middle notes) B_Lower = B_Middle / 2; A_Lower = A_Middle / 2; G_Lower = G_Middle / 2; F_Lower = F_Middle / 2; E_Lower = E_Middle / 2; D_Lower = D_Middle / 2;
%High Notes (Twice the middle notes) C_High = C_Middle * 2; B_High = B_Middle * 2; A_High = A_Middle * 2; G_High = G_Middle * 2; F_High = F_Middle * 2; E_High = E_Middle * 2; D_High = D_Middle * 2;
%Sharp Notes A_Sharp_Lower = 233.08; %Given by instructor on Rhea website
%Defining different note durations for a clearer song
delta = 0.0001; %Time increment
t_full = 0:delta:1; %Full note - 1.0 sec duration t_half = 0:delta:0.5; %Half note - 0.5 sec duration t_quart = 0:delta:0.25; %Quarter note - 0.25 sec duration t_eigth = 0:delta:0.125; %Eigth note - 0.125 sec duration t_sixtnth = 0:delta:0.0625; %Sixteenth note - 0.0625 sec duration
