自動化長笛與準則化音樂控制之研究

Abstract

木管樂器的自動化演奏研究，包含以一支聲響長笛和相關的自動控制裝置與機構，以及電腦自動化產生之音樂創作系統之整合設計為基礎。自動控制裝置又分 為兩個主要的部份 - 吹嘴裝置和按鍵裝置。 吹嘴裝置以運用步進馬達為主；而按鍵裝置以運用伺服機為主。 本研究亦包含兩種準則作曲方式，細胞自動機和機率演算法。 自動演奏長笛可以演奏即時運算的演算法音樂或是一般樂譜的曲子。 演奏設定依據不同的控制模式可分為三種：分斷 (detache)， 斷奏 (staccato) ，和圓滑奏 (legato)。最後該整合式自動演奏長笛系統雛型已成功地完成開發，其相關性能與電腦產生之音樂數據亦於本論文中討論。

The research of automated wind instrument is based on the acoustic flute utomatic control mechanism, and the computer generative music composition. The control mechanism is divided into two major components: mouthpiece and keystroke mechanisms. Stepper motor is the choice for the mouthpiece mechanism and RC Servos for the keystroke mechanism. Two algorithmic composition modules, “Probability module” and “Cellular Automata module” are implemented to the automatic flute system. Besides, algorithmic composition, music score can also be entered in the “Score‐Play” module. The automatic flute could perform music from either one of the algorithmic composition module or from the music score. Three performance settings are also available. They are detache, staccato, and legato, according to the various control modes. Eventually the integrated automated flute system prototype has been successfully developed.discussed in the thesis.
