Secure accommodation is extremely tedious for musicians (8)
I believe the answer is:
cellists
'for musicians' is the definition.
(cellist is a kind of musician)
'secure accommodation is extremely tedious' is the wordplay.
'secure accommodation' becomes 'cell' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'extremely' says to hollow out the word (remove centre letters) (only the extremes of the word are used).
'tedious' with its centre taken out is 'ts'.
'cell'+'is'+'ts'='CELLISTS'
Can you help me to learn more?
(Other definitions for cellists that I've seen before include "String players" , "Julian Lloyd Weber and Jacqueline du Pre, say" .)
