A poem is several poems laid on top of each other: one made of sound, one of grammar, one of lines. Switch each layer on and off to see it alone. Start with one of eight poems, from Shakespeare to Owen, or paste your own draft and let the reader map its sound, sentences and lines.

What the layers show
Sound, syntax and line are mapped automatically: alliteration by matching opening consonant sounds within a line, rhyme by matching word endings, sentences by punctuation, and syllables by vowel groups. The counts are approximate and work on any text you paste. The glosses are Poetic.ly's.
