The Sedōka (in Japanese: 旋 頭 歌;) is a particular type of waka, a rhythmic pattern of Japanese poetry.
The Japanese word in transliteration Hepburn sedōka derives from sedō = repetition of the first sentence and ka = poetry; so sedōka literally means "poetry that goes back to head". A sedōka consists of two thirds, each consisting of verses of five, seven, and seven syllables, for a total of 38 syllables. It is an uncommon metric form that has sometimes been used for dialogues. The Sedoka of Kakinomoto no Hitomaro (VII century), one of the greatest poets of Man'yōshū, is considered as exemplary. Bibliografiamodifica wikitesto
