From the earliest ages, songs have been the heart-notes of nations; the simplest form of poetry, yet the most popular, because written directly from the heart to the heart. Heroic deeds were celebrated in song, love-stories were immortalised in song, ere there was a note of written music or a word of written verse. Thus the twin-sister arts music and poetry, in their infancy scarce distinguishable, passed on hand in hand; but with the lapse of years they grew more divided, their different features becoming more developed, until now, their triumphs have apparently raised a barrier between them, and people forget that they are twin; but the chord of sympathy is still there. The union is not _less_; it is only less visible, because more intricate. It is impossible briefly to state all the points where the sister-muses are at one; let us simply, by pointing out a few examples from the great masters of each, attempt to shew that music and poetry are still closely allied.
The three great moving powers of humanity are Faith, Reason, Passion--the Soul, the Head, the Heart. Faith, reverence, worship, or by whatever name may be called that feeling in man which causes him to adore a being greater than himself, has been expressed in poetry by Milton; in music by Handel. Reason, the thoughts of the human mind, the gropings after a true philosophy, has been expressed in the poetry of Shelley, in the music of Mendelssohn. Passion--each varied emotion that throbs in the heart of man, is expressed in the poetry of Byron, in the music of Beethoven. Others might be cited, and resemblances carried to any extent between poets and musicians; but the above may suffice, being not merely fanciful definitions, but thorough truths, fully borne out in fact; not ideal but real.
There is first the poetry and music in which the feeling of worship, the element of religion, is prime agent. Milton can be fairly taken as the poet of reverence. Owing to the peculiar circumstances of his life and times, the great power of his verse is a cry against the follies and sins of a debased people, an earnest cry for more strength of purpose, more firmness of will. It all strives to exalt a Deity who was like to be forgotten by a nation steeped in the vices and frivolities of Cavalier times. Grand and impressive his verse flows on, a mighty flood, with the hidden strength which shews itself in calm still progress.
