Poster put out quickly for musicians (6)
I believe the answer is:
presto
'quickly for musicians' is the definition.
I can't judge whether this defines the answer.
'poster put out' is the wordplay.
'put out' indicates anagramming the letters.
'poster' anagrammed gives 'PRESTO'.
Can you help me to learn more?
(Other definitions for presto that I've seen before include "Hey, it's a magician's word" , "Very fast (mus.)" , "Hey ..., said the magician" , "Immediately" , "hey......,cries the magician" .)
