Using Musescore (Salamander piano font), I've made an original mashup of 33 classic Christmas tunes just in time for the holidays. Link here: https://youtu.be/zRaazQpWrCs
I thought it was pretty cool to share, and since it's my first polyphonic mashup-type piece (as well as my first post here), I'm open to any feedback and critique. Depending on the response, I can also post the full score here soon. Hope you all enjoy!
