In practice, I should add, the ear is not always so exacting; and ordinary writers, in ordinary moments, content themselves with avoiding what is harsh, and here and there, upon a rare occasion, buttressing a phrase, or linking two together, with a patch of assonance or a momentary jingle of alliteration. To understand how constant is this preoccupation of good writers, even where its results are least obtrusive, it is only necessary to turn to the bad. There, indeed, you will find cacophony supreme, the rattle of incongruous consonants only relieved by the jaw-breaking hiatus, and whole phrases not to be articulated by the powers of man.
