Is there a specific term for that practice/tuning song orchestras play before they start a program?

Question

I'm writing a paper about an orchestra concert I went to, and I wanted to address this specifically. Thanks

Answer 1

They just warm up. Everyone has different methods of warming up - some play scales, some play long tones, others work out technically difficult passages. Then the oboist plays an A (440 hrz), and the strings tune their A strings. Then the oboist plays it again, and the strings tune their other strings to that A. The oboist plays it a third time, and the wind instruments tune.
^^ professional orchestra ^^

A school orchestra might have a different routine, but either way it's called warming up.

Answer 2

I 've always heard it called warming up
