O cool unto the sense of pain
That last night's sleep could not destroy;
O warm unto the sense of joy,
That dreams its life within the brain.
What though I lean o'er thee to scan
The written music cramped and stiff;—
'Tis dark to me, as hieroglyph
On those weird bulks Egyptian.

But as from those, dumb now and strange,
A glory wanders on the earth,
Even so thy tones can call a birth
From these, to shake my soul with change.
O swift, as in melodious haste
Float o'er the keys thy fingers small;
O soft, as is the rise and fall
Which stirs that shade within thy breast.
