One played in blues and new jazz only at first (5)
I believe the answer is:
banjo
'one played in' is the definition.
Although both the answer and definition are singular nouns, I don't understand how they can define each other.
'blues and new jazz only at first' is the wordplay.
'at first' indicates taking the first letters.
The first letters of 'blues and new jazz only' is 'BANJO'.
Can you help me to learn more?
(Other definitions for banjo that I've seen before include "Guitar-like instrument" , "Stringed instrument of the guitar family" , "strumming instrument" , "No jab (anag.)" , "Stringed instrument beloved of old minstrel shows" .)
