Internal rhyme is a poetic device in which rhyming words occur within a single line of verse or between internal phrases across multiple lines. It is different from end rhyme, which occurs between line endings. Internal rhyme schemes can be denoted with spaces or commas between lines. Internal rhyme is a useful poetic tool for increasing the musicality of the language without being overtly "rhyme-y". It can be found in any type of poetry, regardless of its meter or rhyme scheme. There are three key ways in which internal rhyme occurs:

• Two or more rhyming words within the same line.
• A single rhyme that occurs multiple times within one line.
• A rhyme that is spread out through several lines.

Internal rhyme can be used to create rhythm in lines of verse, making language sound more beautiful and thoughtfully-composed, like music. It can also help to increase the sense of rhythm of poetry, thus making it more pleasant to listen to and easier to understand and memorize. Internal rhyme is particularly common in song lyrics, where it is usually used in conjunction with end rhyme to increase the number of rhymes that can be delivered in a single line.
