Lyric Poem · Nature

Mutability

by Percy Bysshe Shelley

The flower that smiles to-day

To-morrow dies;

All that we wish to stay

Tempts and then flies.

What is this world's delight?

Lightning that mocks the night,

Brief even as bright.

Virtue, how frail it is!

Friendship how rare!

Love, how it sells poor bliss

For proud despair!

But we, though soon they fall,

Survive their joy, and all

Which ours we call.

Whilst skies are blue and bright,

Whilst flowers are gay,

Whilst eyes that change ere night

Make glad the day;

Whilst yet the calm hours creep,

Dream thou — and from thy sleep

Then wake to weep.

How this poem works

Measured from the text on this page, not copied from a summary. Counts are approximate: syllables and rhymes come from the CMU Pronouncing Dictionary, which models General American English, so dialect, older pronunciation, and performance can all change what you hear.

Shape
21 lines · 3 septets
End rhyme
ABCBDDD in 67% of the stanzas. The remaining stanzas vary, often through slant rhyme.
Line length
Lines run 4-6 syllables (median 6), consistent with trimeter. No single length dominates, which is normal once elision and contraction are in play.
