Firestarter in silent orchestra (5)

I believe the answer is:

torch

I'm a little stuck... Click here to teach me more about this clue!

'firestarter' is the definition.
I can't tell whether this definition defines the answer.

'in silent orchestra' is the wordplay.
'in' indicates the answer is hidden within the clue.
'TORCH' can be found hidden inside 'silent orchestra'.

Can you help me to learn more?

(Other definitions for torch that I've seen before include "Portable light; burn" , "Deliberately set fire to" , "Set fire to; electric lamp" , "Hand-held lamp or burning stick" , "Set fire to (something)" .)

I've seen this clue in The Sun.
