Closed hole
A filled hole in a wind-instrument fingering diagram means that the indicated tone hole or key is fully closed. It describes fingering, not a notehead or articulation.
- Wind and brass signs
- Above the note
- A circle
Do not confuse it with
An empty hole is open; a half-filled hole is only partly covered.
