Trumpeter's last note after playing musical composition (5)
I believe the answer is:
rondo
'musical composition' is the definition.
(I've seen this before)
'trumpeter's last note after playing' is the wordplay.
'trumpeter's last' becomes 'r' (I can't justify this - if you can you should believe this answer much more).
'note' becomes 'do' (musical note, as in do-re-mi).
'after' means one lot of letters go next to another.
'playing' becomes 'on'.
'do' after 'on' is 'ondo'.
'r'+'ondo'='RONDO'
Can you help me to learn more?
(Other definitions for rondo that I've seen before include "part of a sonata" , "Type of movement" , "Piece written" , "A collection of notes" , "Donor (anag) - piece of music" .)
