“楚商调”新解

A New Interpretation of“Shang Mode of Chu”

楚商调的内涵体现在三个方面:一是二弦夹钟和五弦无射都可解读为宫音的楚商调定弦音列;二是楚商调调意以定弦音列为基础,用以实现同主音商、羽调式交替的旋律模式;三是与旋律模式对应的情感意象。在乐调实践中,特定旋律模式带来的调性游移特征是楚商调的核心精神。东汉王逸注《楚辞·大招》“楚劳商”,备有一说作“以楚声绞商音”,楚商调似商似羽的特征或可从此注作解。

The essence of Chu’s Shang mode is manifested in three aspects.Shang mode of Chu alternates between the Shang and Yu modes,involving the emotional imagery corresponding to the melodic pattern.In musical modes,the tonal modulation brought about by specific melodic patterns is the essence of Chu’s Shang mode.
