An approach to early music? (8)
I believe the answer is:
overture
This might be a double definition.
'an approach' is the first definition.
('overture' can be a synonym of 'approach')
'early music?' is the second definition.
'overture' can be an answer for 'music?' (overture is a kind of music). I am unsure of the 'early' bit.
'to' is the link.
Can you help me to learn more?
(Other definitions for overture that I've seen before include "Musical prelude to opera or ballet" , "eg 'The Hebrides'" , "Opening music" , "Instrumental prelude" , "Orchestral work" .)
