The Jubilant and Estudious options affects how your Tromboner behaves while playing a song.

If Jubilant is enabled, your Tromboner will jump to the beat and sway their trombone side-to-side.

If Estudious is enabled, your Tromboners movement is minimized and the movement you'll see from your Tromboner now is when you change pitch, (moving the cursor up and down) and when a note a played.
