Tèma con Variaziòni

Why is it that Poetry has never yet been subjected to that process of Dilution which has proved so advantageous to her sister-art Music?  The Diluter gives us first a few notes of some well-known Air, then a dozen bars of his own, then a few more notes of the Air, and so on alternately: thus saving the listener, if not from all risk of recognising the melody at all, at least from the too-exciting transports which it might produce in a more concentrated form.  The process is termed “setting” by Composers, and any one, that has ever experienced the emotion of being unexpectedly set down in a heap of mortar, will recognise the truthfulness of this happy phrase.

For truly, just as the genuine Epicure lingers lovingly over a morsel of supreme Venison—whose every fibre seems to murmur “Excelsior!”—yet swallows, ere returning to the toothsome dainty, great mouthfuls of oatmeal-porridge and winkles: and just as the perfect Connoisseur in Claret permits himself but one delicate sip, and then tosses off a pint or more of boarding-school beer: so also -

by Lewis Carroll
I never loved a dear Gazelle—
Nor anything that cost me much:
High prices profit those who sell,
But why should I be fond of such?
To glad me with his soft black eye
My son comes trotting home from school;
He’s had a fight but can’t tell why—
He always was a little fool!
But, when he came to know me well,
He kicked me out, her testy Sire:
And when I stained my hair, that Belle
Might note the change, and thus admire
And love me, it was sure to dye
A muddy green or staring blue:
Whilst one might trace, with half an eye,
The still triumphant carrot through.

c.f. Thomas Moore Lalla Rookh

I never loved a tree or flower,
But 'twas the first to fade away.
I never nurst a dear gazelle
To glad me with its soft black eye
But when it came to know me well
And love me it was sure to die!
