Music makers involved in short race (9)
I believe the answer is:
orchestra
'music makers involved in short race' is the definition.
I can't tell whether this definition defines the answer.
'involved in short race' is the wordplay.
'involved in' is an anagram indicator (involved can mean complex or confusing).
'short'+'race'='shortrace'
'shortrace' anagrammed gives 'ORCHESTRA'.
Can you help me to learn more?
(Other definitions for orchestra that I've seen before include "Company of musicians" , "kitchen setting?" , "Ensemble of players" , "Large group of players" , "Group of musical instrumentalists" .)
