Soaking up the sun
drinking the blue sky, till dusk,
endless bliss in bloom
Haiku is a Japanese verse of 17 syllables or morae which are represented as 5-7-5 .While writing in English, these syllables are presented in 3 lines unlike the original Japanese vertical line presentation.
The main theme of haiku is nature represented by the juxtaposition of ideas with a 'cutting word' or kireji and a 'season word' or kigo, both of which are not essential for the modern haiku writers.
Senryu is a 'Human Haiku' following the syllable count of 17 in the pattern of 5-7-5 in three lines but with the focus on human idiosyncrasies and life situations rather than seasons and natural beauty. Senryu generally don't have a kireji (cutting word ) and a kigo (season word) and are generally dark humored or cynical.
My above verse here, fits the bill for both, hence, is a hybrid! :)
