Let LinkBots Make Music

Problem Description

We want to easily translate music sheets into Ch code! First we start with Python, then we port to C/Ch. Our choice of music sheets is based on https://pianoletternotes.blogspot.com/.

Input Representation

Each group of letter notes is played from left to right, and vertical letters on the same column are played together. The numbers in front of each line are the octave. Lowercase (a c g f) letters are natural notes (white keys). Uppercase (A C G F) letters are the sharp notes (black keys a.k.a. A# C# G# F#). The lines between letters indicates timing to play the notes.
