Rhythm in poetry is the rise and fall of stressed sounds within sentences, paragraphs, and stanzas. And Poetry is commonly written in verse. Verse is essentially poetic form or metrical composition. However, harmony is typically used in the context of music, to refer to the combination of simultaneously played notes to produce chords and chord progressions that have a pleasing effect.
