Quietly contact extremely eager minister (8)
I believe the answer is:
preacher
'minister' is the definition.
(I've seen this before)
'quietly contact extremely eager' is the wordplay.
'quietly' becomes 'p' (p for piano and quiet).
'contact' becomes 'reach' (synonyms).
'extremely' means to remove the middle letters.
'eager' with its centre removed is 'er'.
'p'+'reach'+'er'='PREACHER'
(Other definitions for preacher that I've seen before include "Religious minister" , "Sermoniser; minister" , "cleric" , "Gospeller" , "One spreading religious message" .)
