Broadway show using thematic lilt in a new way (1,6,5,5)
I believe the answer is:
a little night music
'broadway show using thematic lilt in a new way' is the definition.
I can't judge whether this definition defines the answer.
'using thematic lilt in a new way' is the wordplay.
'in a new way' indicates an anagram.
'using'+'thematic'+'lilt'='usingthematiclilt'
'usingthematiclilt' anagrammed gives 'A LITTLE NIGHT MUSIC'.
Can you help me to learn more?
(Other definitions for a little night music that I've seen before include "Sondheim musical" , "theatrical show" , "Not much of note, at the end of the day" .)
