I have to make a song on Matlab and then set up sine waves that correspond to the notes on the scale. The notes are CFDGCEAmCFGC. can someone help me with this?

Here's an example to get you started. 5 seconds of middle C.

fs = 1e4; % sampling frequency
t = 1:1/fs:5; % time signal
freq = 261.6; % note frequency in Hz (middle C)
y = sin(2*pi*freq*t); % create sine wave
player = audioplayer(y, fs); % create audio player object
play(player); % play the sound

clear,clc; t = [0:.000125:.5]

G = sin(2*pi*392*t); A = sin(2*pi*400*t); F = sin(2*pi*370*t);

B = sin(2*pi*493.9*t); C = sin(2*pi*261.6*t);

line1 = [G,G,A,G,F,A,A,B,A,G,B,B,C,B,A]; song = [line1]; sound(song); I have written this code. But I'm unable to figure it out the time factor for each note. How can we find out the time for each note to play.
