Composer able to play with another? Fair enough (4,6)
I believe the answer is:
bela bartok
'composer' is the definition.
(20th-century Hungarian composer)
'able to play with another? fair enough' is the wordplay.
I cannot quite understand how this works, but
an anagram of 'able' is 'bela' which is present in the answer.
'to' is within the answer.
'another?' could be 'r' (I've seen this in other clues) and 'r' is present in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Another definition for bela bartok that I've seen is " composer".)
