Hi, I'm Teemu Koivisto — the author of this app — who found reading music overly difficult so as any software engineer would, I decided to write an app to help me. Hopefully it is of use to you as well.
This is an open-source project utilizing many other open-source libraries such as vexflow, smplr and Svelte to name a few. If you have suggestions or general feedback feel free to submit an issue to the GitHub repository or send me an email at teemukoivisto.xyz ~АТ~ gmail.com
