Tempo odd? Pan musician (9)
I believe the answer is:
trumpeter
'musician' is the definition.
(I know that trumpeter is a type of musician)
'tempo odd? pan' is the wordplay.
'tempo' becomes 't' (this could be a standard abbreviation of which I'm unaware).
'odd?' becomes 'rum' (rum can mean strange or dubious).
'pan' becomes 'peter' (I've seen this in another clue).
't'+'rum'+'peter'='TRUMPETER'
Can you help me to learn more?
(Other definitions for trumpeter that I've seen before include "sends out signals?" , "Jumbo?" , "Brass player" , "Boastful" , "one of a band" .)
