Ode to a Nightingale

My heart aches, and a drowsy numbness pains
    My sense, as though of hemlock I had drunk,
Or emptied some dull opiate to the drains
    One minute past, and Lethe-wards had sunk:
‘Tis not through envy of thy happy lot,
    But being too happy in thine happiness,—
        That thou, light-winged Dryad of the trees,
                In some melodious plot
    Of beechen green, and shadows numberless,
        Singest of summer in full-throated ease.
…
Darkling I listen; and, for many a time
    I have been half in love with easeful Death,
Call’d him soft names in many a mused rhyme,
    To take into the air my quiet breath;
        Now more than ever seems it rich to die,
    To cease upon the midnight with no pain,
        While thou art pouring forth thy soul abroad
                In such an ecstasy!
    Still wouldst thou sing, and I have ears in vain—
    To thy high requiem become a sod.
