MY SOUL IS DARK

I.
My soul is dark—Oh! quickly string
The harp I yet can brook to hear;
And let thy gentle fingers fling
Its melting murmurs o'er mine ear.
If in this heart a hope be dear,
That sound shall charm it forth again:
If in these eyes there lurk a tear,
'Twill flow, and cease to burn my brain.

II.
But bid the strain be wild and deep,
Nor let thy notes of joy be first:
I tell thee, minstrel, I must weep,
Or else this heavy heart will burst;
For it hath been by sorrow nursed,
And ached in sleepless silence long;
And now 'tis doomed to know the worst,
And break at once—or yield to song.
