Terrible ordeal about the upper class getting a run of notes (7)
I believe the answer is:
roulade
'a run of notes' is the definition.
I can't tell whether this defines the answer.
'terrible ordeal about the upper class' is the wordplay.
'terrible' is an anagram indicator.
'about' indicates putting letters inside.
'the upper class' becomes 'u' (as in U- and non-U speech).
'ordeal' is an anagram of 'rolade'.
'rolade' going around 'u' is 'ROULADE'.
'getting' acts as a link.
Can you help me to learn more?
(Other definitions for roulade that I've seen before include "Melodic embellishment" , "Dish; florid musical passage" , "Filled, rolled meat dish" , "Rolled-up piece of meat, fish or sponge with a filling" , "Meat dish with filling" .)
