中文摘要：

作为机器打谱研究的基础工作,提出一种将古琴曲中的谱字转换成绝对音高的方法。分析古琴减字谱的曲调,将其转换成现今的曲调。依照古琴减字谱的记谱方式,将各个减字分为散音、泛音和按音三种音色,并通过古琴琴弦振动的理论和音律学理论的原理,计算各种音色的减字的绝对音高。实验结果表明,所提供的绝对音高的计算方法是有效的。

英文摘要：

This paper proposes an approach to transcribe the written notations in tablature of Guqin musical pieces into absolute pitch,which is a fundamental work in the research of Dapu（transcribing of old tablature into a playable form） with computer. The melodies in Guqin＇s jianzipu（tablature with reduced notations） are analyzed and transformed into contemporary mode. Based on jianzipu＇s record pattern,each reduced notation is sorted to three timbres：san yin（scattered sounds） ,fan yin（floating sounds） and an yin（stopped sounds） ,and the absolute pitch of reduced notation of a variety of timbres is calculated according to the theory of Guqin strings’vibration as well as to the principle of temperament theory. The method of calculating the absolute pitch proposed in this paper has been verified to be effective by the experiment.
