Can they be tuned sharp? (5)

I believe the answer is:

harps

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

'can they' is the definition.
The definition suggests a plural noun which matches the answer.

'tuned sharp?' is the wordplay.
'sharp' can be anagrammed to 'HARPS'.
But, I'm unsure how the anagram is indicated.

'be' is the link.

Can you help me to learn more?

(Other definitions for harps that I've seen before include "Dwells" , "Musical instruments of sharp kind" .)

I've seen this clue in the Evening Standard.
