本文介绍了我们正在开发的一个名为“Papipuun”的音乐摘要系统。Papipuun以一种类似于唱针在划伤的唱片上跳针的方式进行快速聆听，但这种跳针是正确地发生在音乐乐句的标点处，而非随意的。首先，我们基于调性音乐生成理论（GTTM）和演绎面向对象数据库（DOOD）中的时间跨度缩减，开发了一种表示复调的方法。在我们的方法中，表示的复调的相似性检查中，最小上界操作起着重要作用。接下来，在预处理阶段，用户使用一个名为TS - Editor的专用工具通过时间跨度缩减来分析一首固定曲目。在实时阶段，用户与主系统Summarizer进行交互以执行音乐摘要。Summarizer通过相似性检查来发现乐曲结构。当用户确定要跳过的片段时，Summarizer会删除它们并连接其余部分。Papipuun能够生成高质量的音乐摘要，通过与用户的交互反映整首乐曲的氛围。
This paper presents a music summarization system called “Papipuun” that we are developing. Papipuun performs quick listening in a manner similar to a stylus skipping on a scratched record, but the skipping occurs correctly at punctuations of musical phrases, not arbitrarily. First, we developed a method for representing polyphony based on time-span reduction in the generative theory of tonal music (GTTM) and the deductive object-oriented database (DOOD). The operation, least upper bound, plays an important role in similarity checking of polyphonies represented in our method. Next, in a preprocessing phase, a user analyzes a set piece by the time-span reduction, using a dedicated tool called TS-Editor. For the real-time phase, the user interacts with the main system, Summarizer, to perform music summarization. Summarizer discovers a piece structure by means of similarity checking. When the user identifies the fragments to be skipped, Summarizer deletes them and concatenates the rest. Papipuun can produce a music summarization of good quality, reflecting the atmosphere of an entire piece through interaction with the user.
