Player of tango — odd chap (9)
I believe the answer is:
trumpeter
'player' is the definition.
(I know that trumpeter is a type of player)
'tango odd chap' is the wordplay.
'tango' becomes 'T' (phonetic alphabet: alpha, bravo, charlie etc.).
'odd' becomes 'rum' (rum can mean strange or dubious).
'chap' becomes 'peter' (Peter is a man's name).
't'+'rum'+'peter'='TRUMPETER'
'of' acts as a link.
(Other definitions for trumpeter that I've seen before include "kind of pigeon" , "It's the valve operator" , "Brass player" , "sends out signals?" , "Perhaps Nellie" .)
