greeting clear blue skies
The lune is also known as the American Haiku. It was first created by the poet Robert Kelly (truly a great poet) and was a result of Kelly’s frustration with English haiku. After much experimentation, he settled on a 13-syllable, self-contained poem that has 5 syllables in the first line, 3 syllables in the second line and 5 syllable in the final line.
Unlike haiku, there are no other rules. No need for a cutting word. Rhymes are fine; subject matter is open. While there are less syllables to use, this form has a little more freedom.
