Track 1 dispatched to singer (9)
I believe the answer is:
contralto
'singer' is the definition.
(I know that contralto is a type of singer)
'track 1 dispatched to' is the wordplay.
I cannot really see how this works, but
'1' could be 'a' (both can mean one) and 'a' is located in the answer.
'to' is found in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for contralto that I've seen before include "Lowest female singing voice" , "Singer - not car lot (anag)" , "deep, for women" , "Total corn! (anag)" , "Lowest range for a woman singer" .)
