Finish on note admitting end of symphony’s turned bland (7)
I believe the answer is:
anodyne
'bland' is the definition.
(I've seen this before)
'finish on note admitting end of symphony's turned' is the wordplay.
'finish on' becomes 'endon' (I can't justify this - if you can you should give a lot more credence to this answer).
'note' becomes 'a' (musical note).
'admitting' means one lot of letters goes inside another (admit can mean to welcome in or accept).
'end of' says to take the final letters.
'turned' says the letters should be written backwards.
The last letter of 'symphony' is 'y'.
'endon'+'a'='endona'
'endona' enclosing 'y' is 'enydona'.
'enydona' reversed gives 'ANODYNE'.
Can you help me to learn more?
(Other definitions for anodyne that I've seen before include "Describes what soothes or dulls the senses" , "Unlikely to cause offence - rather dull" , "A drug that relieves pain" , "Relieving hurt" , "Innocent" .)
