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 94 bpm (pi*30 rounded), and then becomes 63 bpm at the end (pi*20 rounded). 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. 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) Also, happy Pi Day! (Pi Day Friday!)
