Loud musical instrument? (5)
I believe the answer is:
flute
'loud musical instrument?' is the definition.
'flute' can be an answer for 'instrument?' (flute is a kind of instrument). I'm not sure about the 'loud musical' bit.
'loud musical instrument?' is the wordplay.
'loud' becomes 'f' (short for forte - 'loud' in music).
'musical instrument?' becomes 'lute' (lute is a kind of musical instrument).
'f'+'lute'='FLUTE'
Can you help me to learn more?
(Other definitions for flute that I've seen before include "High-pitched woodwind instrument" , "Musical instrument - wineglass" , "Champagne glass" , "See 20" , "Wind instrument" .)
