Bach.sh

How to play

Just run

./bwv846-prelude.sh | aplay

Or

./bwv846-prelude.sh | mpv -

Be careful, it might sound too loud!

If nothing works, you can just save output to a wav file and play it with any player:

./bwv846-prelude.sh > prelude.wav

Why

Because why not? Bash is a very limited language so using it to make music is really fun.

Compression

Surprisingly, bzip2 compresses its output to a size even smaller than the original .sh file. And if you turn off PWM in the code (comment line 42), you'll get this 13-line base64-encoded archive:
