Fine piano had us transported (10)
I believe the answer is:
diaphanous
'fine' is the definition.
(thesaurus)
'piano had us transported' is the wordplay.
'transported' indicates an anagram.
'piano'+'had'+'us'='pianohadus'
'pianohadus' anagrammed gives 'DIAPHANOUS'.
(Other definitions for diaphanous that I've seen before include "Light, delicate, translucent" , "Fine and translucent" , "(Of fabric) delicate, translucent" .)
