Instrument — another would be loud against it (4)

I believe the answer is:

lute

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

'instrument' is the definition.
(I know that Lute is a instrument)

I don't understand how the remainder of the clue works.

Can you help me to learn more?

(Other definitions for lute that I've seen before include "Ancient stringed instrument" , "Stringed instrument shaped like a halved egg" , "Protective packing" , "Play instrument" , "Elizabethan stringed instrument" .)

I've seen this clue in The Times.
