First half of recent arrangement for wind instrument (8)
I believe the answer is:
recorder
'wind instrument' is the definition.
(recorder is a kind of wind instrument)
'first half of recent arrangement' is the wordplay.
'first half of' suggests halving the letters.
'arrangement' becomes 'order' (order is a kind of arrangement).
'recent' with half the letters taken is 'rec'.
'rec'+'order'='RECORDER'
'for' acts as a link.
(Other definitions for recorder that I've seen before include "The one who takes notes and a tubular wind instrument" , "Judge - musical instrument" , "Registrar" , "Maybe video" , "Fipple-flute" .)
