It may be protested that after all the peculiar property of lyric, differentiating it from other kinds of poetry, is that it is song. If we dismiss the association of the art of poetry with the art of music, as we may well do, I think the protest is left without any significance. In English, at any rate, there is hardly any verse—a few Elizabethan poems only—written expressly to be sung and not to be spoken, that has any importance as poetry, and even the exceptions have their poetic value quite independently of their musical setting. For the rest, whenever a true poem is given a musical setting, the strictly poetic quality is destroyed. 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. The result may be, and often is, of rare beauty and of an artistic significance as great, perhaps, as that of the poem itself, and the poet is mistaken in refusing, as he often does,[4] to be the cause of the liberation of this new and admirable activity in others. But, in the hands of the musician, once a poem has served this purpose, it has, as poetry, no further existence. It is well that the musician should use fine poetry and not bad verse as his inspiration, for obvious reasons, but when the poetry has so quickened him it is of no further importance in his art save as a means of exercising a beautiful instrument, the human voice. It is unnecessary to discuss the relative functions of two great arts, wholly different in their methods, different in their scope. But it is futile to attempt to blend the two.
4: His refusal is commonly due to lamentable experience. If a Shelley is willing to lend his suggestions to the musician, he has some right to demand that the musician shall be a Wolf. The condition of his allowing his poem to be used and destroyed in the process is, rightly, that something of equal nobility shall be wrought of its dust.
As far as my indifferent understanding of the musician's art will allow me I delight in and reverence it, and the singing human voice seems to me to be, perhaps, the most exquisite instrument that the musician can command. But in the finished art of the song the use of words has no connection with the use of words in poetry. If the song be good, I do not care whether the words are German, which I cannot understand, or English, which I can. On the whole I think I prefer not to understand them, since I am then not distracted by thoughts of another art.
If then from the argument about the lyric that it should "sing," we dismiss this particular meaning of its adaptability to music, what have we left? It cannot be that it peculiarly should be rhythmic, since we have seen that to be this is of the essential nature of all poetry—that rhythm is, indeed, necessary to the expression of the poetic emotion itself. It cannot be that it peculiarly should be of passionate intensity, since again, this we have seen to be the condition of all poetry. In short, it can mean nothing that cannot with equal justice be said of poetry wherever it may be found. To the ear that is worthy of poetry the majestic verse of the great passages in Paradise Lost, the fierce passion of Antony and Macbeth, the movement of the poetry in Sigurd the Volsung, "sing" as surely as the lyrics of the Elizabethans or of Poems and Ballads. Poetry must give of its essential qualities at all times, and we cannot justly demand that at any time it should give us more than these.
