Timesig is a work in progress esoteric language by User:upbeatsarcastic.
Timesig programs read like musical scores. The program pointer is called the BAR, the program tape is called the STAVE.
A Timesig program can never be infinite in length.
The BAR acts as the program pointer. It reads from left to right across the source bars, which are defined like so:
STAVE 32 | TEMPO 120 %crescendo% $|4/4 e g f# b-f|a-a c-b-a-g d b:||
Timesig has 13 commands, one for each musical note and 1 repeat for loops.
Musical notes, another esolang based on music.
