It should here be added that poetry habitually takes the form of verse.
When the poet makes his perfect selection of a word, he is endowing the word with life.
The musician – if he be a good one – finds his own perception prompted by the poet’s perception, and he translates the expression of that perception from the terms of poetry into the terms of music.
A lyric, it is true, is the expression of personal emotion, but then so is all poetry, and to suppose that there are several kinds of poetry, differing from each other in essence, is to be deceived by wholly artificial divisions which have no real being.
Any long work in which poetry is persistent, be it epic or drama or narrative, is really a succession of separate poetic experiences governed into a related whole by an energy distinct from that which evoked them.
