Instruction to get a lute out (8)
I believe the answer is:
tutelage
'instruction' is the definition.
(tutelage is instructing or teaching)
'get a lute out' is the wordplay.
'out' indicates anagramming the letters (out can mean wrong or inaccurate).
'get'+'a'+'lute'='getalute'
'getalute' is an anagram of 'TUTELAGE'.
'to' is the link.
(Other definitions for tutelage that I've seen before include "Guardianship; instruction" , "Schooling" , "Instruction by personal teacher" , "Training" , "guidance" .)
