In this guide, we are going to learn how to display sheet music while playing a song in Synthesia.
While playing a song, just select the sixteenth note (semiquaver) icon that appears on the toolbar at the top of the screen. This will show or hide sheet music for the part you've selected to play.
If the icon doesn't appear, you'll need to assign a hand to at least one part in the song. Follow step 4 from the First-time setup guide.
The sheet music display area can be resized to your liking.
If you prefer sheet music to the falling notes, you can use the "Toggle All Notes Hidden" shortcut ( F5 by default on the desktop) to completely hide the falling notes.
Hit F5 again to show the falling notes again. This shortcut always works, even when you're not using Synthesia's sheet music feature.
