You may be transported by this Busoni piece (3)
I believe the answer is:
bus
'you may be transported by this busoni piece' is the definition.
The definition suggests a singular noun which matches the answer.
'by this busoni piece' is the wordplay.
'by' is a charade indicator (letters next to each other).
'this busoni' becomes 'us' (I can't justify this - if you can you should believe this answer much more).
'piece' becomes 'b' (abbreviation for bishop).
'us' put after 'b' is 'BUS'.
Can you help me to learn more?
(Other definitions for bus that I've seen before include "Coach" , "eg Double-decker" , "Mode of public transport" , "Public transport vehicle" , "Use transport" .)
