音樂內涵式查詢與分析為目前於多媒體訊號處理與音樂分析等相關領域中之主要研究主題之一。目前主要的音樂內涵分析研究大都以西方音樂為探討對象，大多數研究以鋼琴、弦樂器、鼓等樂器演奏樂曲。古琴為古代傳承下來的一種樂器，其琴譜所採用的記錄方式與西方音樂不同，不過也因此造就了特殊的記錄方式，也就是減字譜。此種記錄方式並沒有記載曲子的節奏，所以根據演奏者的不同，同首曲子可能會演奏出不同風格的版本，加上時代久遠，因此對其數位化儲存及管理的進行產生一定難度。其中對於古琴減字譜數位化的問題，本研究提出可藉由MusicXML 的格式進行改良，並將記錄古琴減字譜的系統稱為QinXML 來進行儲存。至於無人演奏的琴曲則需要再重新製作減字譜，將其原先的演奏方式記錄下來；而將沒有標示節奏的琴曲藉由嘗試演繹琴曲節奏的手法稱之為打譜。
本研究希望藉由參考西方音樂分析理論的約化技術並考慮古琴音樂的特性，對古琴旋律進行分析；找出適合的古琴減字譜音樂分析理論，再利用古琴曲自動打譜，套用於其他尚未經過打譜的琴曲並產生節奏，將經過打譜之後的琴曲提供古琴演奏家作為演奏方式的參考。

Content-based music information retrieval and analysis is one of the major research topics in the field of multimedia signal processing. Most works on musical content analysis were done in Western music, such as piano, cello, violins, and drums. As Qin is one of the oldest Chinese instrument, the abbreviated character tablatures for the Qin scores, called Jian-Tz-Pu, is very unique. There are many differences between Jian-Tz-Pu and western score. Jian-Tz-Pu didn’t store the rhythm information of a song. Therefore the same song can have many different style of interpretations. We used QinXML to store the Qin scores. For Qin scores never played before, we need to discover their rhythms before they can be played. This paper aims to apply western music theory on the Qin melody to reduce them into their simplest forms. Then Qin music could be automatically played by inducing their corresponding rhythm for the scores in Jian-Tz-Pu.
