404. Bartók can shock

A fine violinist named Eric,
Has a group that plays works esoteric.
Quartets writ by Béla
Just never do fail-a
To leave unwashed listeners choleric.

One of my favorite websites is A Word A Day, home page http://wordsmith.org/awad/.
You may sign up there (totally free) and begin receiving words every weekday, plus a weekend compendium of readers' comments.  Today's word appears at the end of line 3.

There once was a wordsmith named Eric
Who only wrote words esoteric
These terms recondite
He would use out of spite
Just to make doltish readers choleric.

My name's not Eric, but comment if you think I need to back off the fancy words...
