This is a Plover plugin that plays Pachelbel's Canon using musicpy.
The canon will start playing when Plover receives a stroke, and will speed up and slow down depending on stroke speed.
You have to install manually from the command line.
See the instructions here.
For Windows:
.\plover_console.exe -s plover_plugins install git+https://github.com/greenwyrt/plover_canon.git
