Singer taking part in recital tomorrow (4)
I believe the answer is:
alto
'singer' is the definition.
(alto is a kind of singer)
'part in recital tomorrow' is the wordplay.
'part in' indicates a hidden word.
'ALTO' can be found hidden inside 'recital tomorrow'.
'taking' acts as a link.
(Other definitions for alto that I've seen before include "The highest adult male singing-voice" , "A singing voice or pitch" , "Low female singing voice" , "Voice part" , "Counter-tenor or contralto" .)
