Alliteration, assonance, consonance, onomatopoeia, and rhyme are all examples of sound figures. These effects are created by repeating or closely matching one or more words or syllables within a sentence or poem. Alliteration is when two similar sounding words are heard together frequently. For example, "jingle-jangle", "tinkle-tangletinkle". Alliteration can be used to create a pleasant effect. In fact, it is one method used by poets to express themselves lyrically. Assonance is when two or more words that begin with the same letter are sounded together. For example, "springtime" and "marching band". Assonance can also be used to create a pleasant effect. Consonance is when two or more words that end with the same letter are sounded together. For example, "cradle" and "grave". Consonance can also be used to create a pleasant effect.
