Beautiful singing about noble act (3,5)
I believe the answer is:
bel canto
'beautiful singing' is the definition.
'bel canto' can be an answer for 'singing' (bel canto is a kind of singing). I'm not certain of the 'beautiful' bit.
'about noble act' is the wordplay.
'about' indicates anagramming the letters.
'noble'+'act'='nobleact'
'nobleact' with letters rearranged gives 'BEL CANTO'.
Can you help me to learn more?
(Other definitions for bel canto that I've seen before include "Operatic singing style - noble act (anag)" , "Lyrical operatic style" , "Lyrical style of opera singing" , "Style of operatic singing, as that of Callas, say" , "Type of singing" .)
