「序章」 is the opening chapter of a novel or paper, and figuratively the start of something, as in 「悲劇の序章」. A preface before a book is 「序文」 or 「前書き」 (「緒言」 formal, 「序言」 rare); spoken lead-ins are 「前置き」. 「冒頭」 is the very start of a text or talk, 「書き出し」 its first sentences, 「導入」「導入部」 the lead-in. 「総論」「概論」「序論」「序説」 are academic overview sections; 「イントロダクション」「イントロ」 are loanwords, the latter for music. 「序で」 read 「ついで」 is about chance or order, not a preface. Opposite: 「終章」; 「結末」 is the ending of a story or matter.
