“And had to grin like a dog instead,” suggested Waters, stroking his short black beard, which was streaked with grey. The applicability of the classical English epithet “silver-sabled” to his beard consoled him for those signs of the middle years.

“No, I assure you, grinning was beyond me,” said this musical sufferer, “though I admit the neatness of your quotation. It was a mere confused noise like nothing so much as the protracted tuning of the orchestra. But, it’s no use getting angry with stuff that doesn’t merit the faintest attention.”

Jackson put his head on one side, his favourite attitude when pronouncing critical judgments.

“I’m not altogether so sure that I agree with you,” he said, “I’m not speaking about Debussy because I’ve never heard of him before, but I think some modern music is uncommonly fine. But you’re such a confounded purist, my dear fellow.”

“Certainly I can’t find time for the second best,” said Butler. “There’s nothing been written in the last fifty years that has a chance of living.”

“A sweeping statement, rather,” said Waters. “I was considerably impressed by the festival at Bayreuth two years ago: in fact I’m going again in August. There are certain parts of Tristan and Isolde that are very moving. Can’t I persuade you to come with me?”

Jackson laughed.

“Not if you were Peitho herself would you persuade him,” he said. “What was that phrase of yours, Butler, when you heard Tristan in London. ‘Three hours of neurasthenic cacophany,’ I think you called it.”

“I believe I did,” said Butler, gratified that his dictum should be remembered. “But if I did, I understated it. Ah, here is our coffee: I wonder why Alison doesn’t come.”

“He went to see the Master about something connected with the May-week concert,” said Waters. “He told us he might be a little late. I can’t quite agree with our host about Wagner, but I do cordially agree with him that there’s a cult of the incompetent sprung up, who make up for their want of artistic ability by sheer bizarre impertinence. Debussy I make no doubt is one of them (though like Jackson I never heard a note of him), and the modern impressionists and post-impressionists and cubists are others. If I may adapt Butler’s phrase I should have no hesitation in describing their canvasses as ‘Three feet of neurasthenic daubings.’ But of course their scribblings are merely pour rire.”
