xylophonobia 

The extreme feeling of existential dread that a person feels whilst in the presence of, or hearing a xylophone.

“I’m terribly sorry, Mr. Montgumery, but I will be unable to attend the orchestral demonstatration of the talents of said musicians; as I know there will be a xylophone present, and I suffer from xylophonobia.”
