Cultural item from Mozart, not half European? Truth (8)
I believe the answer is:
artefact
'cultural item' is the definition.
(cultural artefact)
'mozart not half european? truth' is the wordplay.
'not half' suggests halving the letters.
'european?' becomes 'E' (abbreviation e.g. EU).
'truth' becomes 'fact' (true facts).
'mozart' halved is 'art'.
'art'+'e'+'fact'='ARTEFACT'
'from' is the link.
(Other definitions for artefact that I've seen before include "Man-made object, of archaeological interest say" , "Something created" , "not natural" , "Man-made object (maybe found in dig)" , "Handcrafted object" .)
