Pi is a number, made up of a bunch of digits. But what do these digits... sound like? This takes the first 150 digits of pi after the decimal point, and it assigns each digit from 1 to 9 a note on the E major scale (0 having no note played, i.e. a rest). It also takes chords with the roots of these notes, making them major/minor/diminished to correspond with the key. I have tried to make it sound good, though it is somewhat hard, as these notes do not form any sort of pattern. The song starts at a tempo of 60 bpm (60 per minute), and then becomes 60 bpm at the end (60 per minute). Although every single note length is fractional so it's not really. Pi is a mathematical constant that approximately equals 3.14. It is represented by the Greek letter π, and is equal to the ratio of the circumference of a circle to its diameter, i.e. the length of the circumference of a circle divided by the length of the diameter. Pi goes on forever, having an infinite amount of digits. Because it cannot be represented by a fraction of two numbers (e.g. 22/7), it is considered irrational. Because it cannot be represented by any polynomial operation (e.g. square roots, exponents, etc.), it is also considered transcendental. It's also very closely approximated by 9801/1103√8. For a potentially better performance, click the green flag multiple times. The number may still be slightly out of sync, but I tried my best to sync it with the song. Fun fact: Pi has been calculated to 202,112,290,000,000 decimal places! (>202 trillion) And the last digit so far is 2 Also, happy Pi Day! (Pi Day Friday!)
