Opera gig playing musical exercise (8)
I believe the answer is:
arpeggio
'musical exercise' is the definition.
Although both the answer and definition are singular nouns, I don't understand how they can define each other.
'opera gig playing' is the wordplay.
'playing' is an anagram indicator.
'opera'+'gig'='operagig'
'operagig' is an anagram of 'ARPEGGIO'.
Can you help me to learn more?
(Other definitions for arpeggio that I've seen before include "Notes of a chord played in rapid succession" , "Notes played in quick succession" , "Piano exercise" , "Split chord" , "Notes of a musical chord played in succession" .)
