Meeting to hear soprano and tenor (5)
I believe the answer is:
tryst
'meeting' is the definition.
(tryst is a kind of meeting)
'hear soprano and tenor' is the wordplay.
'hear' becomes 'try' ('try' can be a synonym of 'hear').
'soprano' becomes 's' (musical abbreviation).
'and' means one lot of letters go next to another.
'tenor' becomes 't'.
'try'+'s'+'t'='TRYST'
'to' is the link.
(Other definitions for tryst that I've seen before include "Secret assignation" , "Romantic rendezvous (literary)" , "meeting with another person" , "meeting-place" , "Lump (of gold, etc)" .)
