「一中節」為都太夫一中於江戶時代中期在京都所創造的淨琉璃流派之一，至今仍被流傳著。初世一中當時初期一中節之劇本，加上收錄於「丸本(完全劇本)」、「段物集（段落物集）」等，約有上百曲的作品。其中丸本(完全劇本)八篇已於本人著作「一中節基礎之研究 第一卷 正本集」中針對写真版、翻印古籍版進行解說及記述。 另外，刊登於段物集中約九十篇作品已收錄本人論文「翻刻一中節之語集(一)~(三)」中。\r 本篇論文首先將其劇本以丸本物、端物 段物、或時代物、世話物等觀點予以分類，之後依其分類將針對收錄於段物集、歌謠集之段物、端物類加以考察，歸納出初世都太夫一中及其弟子半中其談話集的特徵。 ICCHUU-BUSHI is one of the schools of joruria (a dramatic narrative chanted to a samisen accompaniment) which is created by Miyako Tayu Icchuu in EDO Era, it was still spread up to now.
