Question

What is playing or singing without making any sound called?

Performance anxiety
Shadow rehearsing
Thinking error
Warm-up

Answer 1

I would think shadow rehearsing. My logic was shadows dont talk or sing- and rehearsing obviously like practicing… my apologies

Answer 2

Warm up

Step-by-step explanation:

Maybe warm- up because you are practicing for a big rehearsal. It could be silent, or no sound.
