From a review in today's Times of a concert devoted to the work of Esa-Pekka Salonen:
(Salonen's music contains) "a recurring impulse to battle its own tendency towards lyricism, quashing a melodic passage in "Prologue," for instance, with a flatulent blat from the oboe."
I suppose "flatulent blat" is otiose - can there be a non-flatulent blat?- which just goes to show that non-otiosity (which may spell-checker says isn't a word) in writing isn't everything.
Would that we had economists with a tendency towards lyricism, to battle or not. Maybe some of Samuelson's history of thought papers would qualify, with elegant derivations undercut here and there with sly wit. Any other candidates?
