4CONCLUSIONS% 1. Block size = 1024 is best for representing this music signal as it% is very smooth

% 2. Drum is hit as integer times, 1,2,3,4... which can be identified as% drum beats have very low frequency

% 3. Time 1-2 and 2-3 piano tune can be identified in these regions

% 4. 3 instruments are there. Piano, drum beats and pop sound
