What's that song!?

Hi there, I am JellyFish, a piano teacher who love sharing fun ways to enjoy practicing piano. I compose this finger exercise with a HIDDEN SONG for my student focusing on trill and arpeggios technique, and so they can prepare for the HIDDEN score. You can find my social media links in my “Home” page. Subscribe my channel and stay tune for answer and HIDDEN score tutorial! Cheers! JellyFish Family
