The most terse piece of criticism I ever heard of happened at a Comhaltas competition in Listowel some years ago.
The proceedure is that the 'victim' stands before a panel, plays their piece, the chairman, after discussion, comments learnedly on the playing, the choice etc, and then they adjudicate.
A young fiddle player entered the competition, came before the panel, obviously petrified, played and waited for the sentence.
The chairman, a notorious publican from Kerry leaned back in his chair, folded his arms and said loudly - "NEXT"
