A powerful, moving Busoni piece (3)
I believe the answer is:
bus
'a powerful moving busoni piece' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'piece' is the wordplay.
I cannot really understand how this works, but
'piece' could be 'b' (abbreviation for bishop) and 'b' is found within the answer.
The remaining letters 'us' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for bus that I've seen before include "Something caught" , "Public transport vehicle" , "Use transport" , "Mode of public transport" , "eg Double-decker" .)
