In my spare time, I like to make educational materials and brass arrangements of public domain (read as “free”) music using the software formerly known as MuseScore (now known as MuseScore studio). I use MuseScore because it’s free and I’m a cheapskate, and if you have any interest in said material, you can find all of that on my MuseScore profile which is linked down below.
Because MuseScore’s website is not the best, I also make it a habit to upload my arrangements to IMSLP (International Music Score Library Project). My IMSLP profile is linked down below as well.

IMSLP is potentially the biggest repository for public domain sheet music in the world. I highly recommend getting familiar with this website if you’re looking for high-quality free sheet music.

MuseScore studio (formerly known as just “MuseScore”) is the best free notation software that I’m aware of. If you or someone you know is trying to make professional-looking sheet music, MuseScore studio is a great place to start.
