Player gets second note about love (6)
I believe the answer is:
stereo
'player' is the definition.
(I've seen this before)
'second note about love' is the wordplay.
'second note about' becomes 'stere' (I can't justify this - if you can you should give a lot more credence to this answer).
'love' becomes 'o' (love means zero in tennis).
'stere'+'o'='STEREO'
'gets' acts as a link.
Can you help me to learn more?
(Other definitions for stereo that I've seen before include "Sound transmitted through two speakers" , "Sound coming from different directions" , "Method of sound reproduction" , "System that gives a three-dimensional sound" , "Sound - not mono" .)
