Pair of small drums carved into entablature (5)
I believe the answer is:
tabla
'pair' is the definition.
(I have seen 'pair of drums' mean 'tabla' so perhaps 'pair' could also mean 'tabla')
'into entablature' is the wordplay.
'into' says the answer is hidden in the clue.
'TABLA' is hidden within 'entablature'.
'of small drums carved' is the link.
I am not very happy about this link. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for tabla that I've seen before include "one battered by Indians" , "percussion instrument" , "Indian musical instrument" , "Indian hand drums" , "has stretched skin" .)
