Create's music out of 100,000 digits of pi, so you will never run out of music to play! It's so long that I included a Load and Save feature. So you can keep listening and not have to listen to the same notes over and over! This piano board is from (low) C to (high) C. However, B and (high) C are not played.
Fun Fact: This will take about 28 hours to listen to! :)
