and spared me the necessity of submitting it to analysis. I
considered it, however, with regard to its susceptibility of
improvement, and soon saw it to be in a primitive condition. As commonly
used, the _refrain_, or burden, not only is limited to lyric verse, but
depends for its impression upon the force of monotone--both in sound and
thought. The pleasure is deduced solely from the sense of identity--of
repetition. I resolved to diversify, and so heighten the effect, by
adhering in general to the monotone of sound, while I continually varied
that of thought: that is to say, I determined to produce continuously
novel effects, by the variation _of the application_ of the
_refrain_--the _refrain_ itself remaining, for the most part, unvaried.

These points being settled, I next bethought me of the _nature_ of my
_refrain_. Since its application was to be repeatedly varied, it was
clear that the _refrain_ itself must be brief, for there would have been
an insurmountable difficulty in frequent variations of application in
any sentence of length. In proportion to the brevity of the sentence
would of course be the facility of the variation. This led me at once to
a single word as the best _refrain_.

The question now arose as to the _character_ of the word. Having made up
my mind to a _refrain_, the division of the poem into stanzas was of
course a corollary, the _refrain_ forming the close to each stanza. That
such a close, to have force, must be sonorous and susceptible of
protracted emphasis, admitted no doubt, and these considerations
inevitably led me to the long _o_ as the most sonorous vowel in
connection with _r_ as the most producible consonant.

The sound of the _refrain_ being thus determined, it became necessary to
select a word embodying this sound, and at the same time in the fullest
possible keeping with that melancholy which I had predetermined as the
tone of the poem. In such a search it would have been absolutely
impossible to overlook the word "Nevermore." In fact, it was the very
first which presented itself.

The next _desideratum_ was a pretext for the continuous use of the one
word "nevermore." In observing the difficulty which I at once found in
inventing a sufficiently plausible reason for its continuous repetition,
I did not fail to perceive that this difficulty arose solely from the
pre-assumption that the word was to be so continuously or monotonously
spoken by a _human_ being--I did not fail
