_metrical_, having music in it,
being a Song. Truly, if pressed to give a definition, one might say
this as soon as anything else: If your delineation be authentically
_musical_, musical not in word only, but in heart and substance, in
all the thoughts and utterances of it, in the whole conception of it,
then it will be poetical; if not, not.--Musical: how much lies in
that! A _musical_ thought is one spoken by a mind that has penetrated
into the inmost heart of the thing; detected the inmost mystery of it,
namely the _melody_ that lies hidden in it; the inward harmony of
coherence which is its soul, whereby it exists, and has a right to be,
here in this world. All inmost things, we may say, are melodious;
naturally utter themselves in Song. The meaning of Song goes deep. Who
is there that, in logical words, can express the effect music has on
us? A kind of inarticulate unfathomable speech, which leads us to the
edge of the Infinite, and lets us for moments gaze into that!

Nay all speech, even the commonest speech, has something of song in
it: not a parish in the world but has its parish-accent;--the rhythm
or _tune_ to which the people there _sing_ what they have to say!
Accent is a kind of chanting; all men have accent of their
own,--though they only _notice_ that of others. Observe too how all
passionate language does of itself become musical,--with a finer music
than the mere accent; the speech of a man even in zealous anger
becomes a chant, a song. All deep things are Song. It seems somehow
the very central essence of us, Song; as if all the rest were but
wrappages and hulls! The primal element of us; of us, and of all
things. The Greeks fabled of Sphere-Harmonies: it was the feeling they
had of the inner structure of Nature; that the soul of all her voices
and utterances was perfect music. Poetry, therefore, we will call
_musical Thought_. The Poet is he who _thinks_ in that manner. At
bottom, it turns still on power of intellect; it is a man's sincerity
and depth of vision that makes him a Poet. See deep enough, and you
see musically; the heart of Nature _being_ everywhere music, if you
can only reach it.

The _Vates_ Poet, with his melodious Apocalypse of Nature, seems to
hold a poor rank among us, in comparison with the _Vates_ Prophet; his
function, and our esteem of him for his function, alike slight. The
Hero taken as Divinity; the Hero taken as Prophet; then next the Hero
taken only as Poet: does it not
