Jisoo Kim founded MU:note, a practice log for iPhone and Android that counts only the time you actually play your instrument. Jisoo holds a master's degree in music, works as a music educator, and has published research on music.
Why MU:note exists
Teaching shaped one view: keeping a practice journal and looking back on it matters, but practice time is hard to remember accurately, and the work musicians put in stays invisible — in the practice room and on stage. MU:note exists to make that work visible.
How the guides are written
Every guide on this site is written by Jisoo Kim. Research is cited only after the original source has been checked, well-known performers' stories are included only when they can be traced to a reliable source, and MU:note statistics are aggregate figures from sessions recorded with the app — never individual data.
