Internal rhyme

In poetry, internal rhyme, or middle rhyme, is rhyme that occurs within a single line of verse, or between internal phrases across multiple lines. By contrast, rhyme between line endings is known as end rhyme.

Internal rhyme schemes can be denoted with spaces or commas between lines. For example, "AB,AB,AB" denotes a three-line poem with the same internal rhyme on each line, and the same end rhyme on each line (which does not rhyme with the internal rhyme).
