Modern versions of trumpets? (7-4)
I believe the answer is:
'versions of trumpets?' is the definition.
I know nothing about this answer so I can't tell whether this works.
'modern' is the wordplay.
I cannot quite understand how this works, but
'modern' could be 'in' (I've seen this in other clues) and 'in' is located in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
