Where the maestro stands in great unpopularity, next to the piano (6)
I believe the answer is:
This might be a double definition.
'where the maestro stands in great unpopularity next' is the first definition.
Although both the answer and definition are singular nouns, I cannot understand how they can define each other.
'the piano' is the second definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Perhaps there's an association between them I don't understand?
'to' acts as a link.
Can you help me to learn more?
(Other definitions for podium that I've seen before include "Winners' platform" , "Stage" , "Position of speaker" , "'Dais, pulpit (6)'" , "Small platform for speaker" .)
