Fermata
also called: pause · hold · bird's eye · corona
An arc with a dot beneath it, placed over a note, chord, or rest, telling you to hold it longer than its written value.
What you do
Sustain the note — or sit in the rest — past its written length. How much longer is a musical judgment, not a formula. In an ensemble, watch the leader or conductor; the fermata ends when they move on, not when the arithmetic says so.
