Abstract

本稿では歌詞の韻律を用いた歌唱曲の新しい自動作曲手法を提案する。旋律を音の経路と捉え作曲を経路探索問題として定式化することで、任意の日本語の歌詞を用いた歌唱曲の自動作曲が、歌詞の韻律に基づく制約条件下での最尤経路探索問題を解くことで実現できることを示す。さらにこの作曲原理を実装した自動作曲システム "Orpheus" を用いて実際に楽曲生成を行い、作曲家による生成された楽曲に対する評価を踏まえて、今回の手法によって妥当な音楽性をもった歌唱曲が生成されたことを検証する。In this paper, we discuss a new algorithm for automatic song composition and introduce our new composition system named "Orpheus". We show that composing melody on Japanease lyrics can be done automatically by considering musical composition task as an optimal-path search problem under constraints of the upward and downward pitch motions given from the prosody of the lyrics. Valuation on the results generated by "Orpheus" by a musical composer is also reported, which indicates that our new system can compose a song with a proper degree of musicality.
