Concert piano: £1000 (5)
I believe the answer is:
grand
'concert piano' is the definition.
(I've seen this in another clue)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for grand that I've seen before include "GBP1,000" , "Impressive, large" , "PS1k" , "Marvellous" , "Magnificent, imposing" .)
