音乐形态学四种定律及相关解释

Four Laws of Music Morphology and Related Explanations

音乐形态学具有与数学、物理学相通的内在特质。其研究愈趋于深层,就愈显示出其简单而深刻的基本法则或客观规律。这种客观规律,即所谓"定律"。定律一:调式中每个音级的特性,就是它与其他音级之间的结构的特性。定律二:调式结构张力的大小,与调式中心至五度链中心距离的大小成正比。定律三:旋律即音的高低结构与长短结构(音调与节奏)合二为一的同步运动。定律四:通用的音材料数量以十二音为限;音阶(或调式)的音级数量以七声为限(二者间具有连锁关系)。

Music morphology has inherent characteristics that are similar to mathematics and physics.The more in-depth the research is,the more simple and profound basic or objective rules are revealed.This objective rule is so-called"law".Law number 1:The characteristic of each sound level in the mode is the characteristic of the structure between it and other sound levels.Law number 2:The tension of the modulated structure is proportional to the distance from the modulated center to the center of the five-degree chain.Law number 3:The melody is a synchronous movement in which the high and low structure of the sound and the long and short structure(tone and rhythm)are combined into one.Law number 4:The number of universal sound materials is limited to twelve tones;the number of musical scales(or modes)is limited to seven tones(the two have a chain relationship).
