本文译自美国1972年普兰蒂斯版《对位法》(Counterpoint)一书(第一版)。作者肯特·惠勒·肯南(Kent Wheeler Kennan)是美国奥斯汀德克萨斯大学的音乐教授。这里所摘译的第十八章“以圣咏为基础的曲式”(及第十九章“对位的变奏曲式”)其内容均是截至目前为止在国内已出版的对位法教科书中所未曾有过的。文中曾多次提及的“习题手册”,亦是1972年由普兰蒂斯出版的。由于手头没有这本书,故未能将有关的习题一并发表,这一任务只好靠对位法教师自己去完成了。 This article was translated from the 1972 edition of Platts’ Counterpoint, USA (first edition). Author Kent Wheeler Kennan is a professor of music at the University of Texas, Austin, USA. Chapter XVIII, “Songs Based on Chant” (and Chapter 19, “Variations of Verses”), which are extracted here, are the texts of the para-textbooks that have been published so far in China Never had it before The “Handbook of Exercises” mentioned many times in the text was published by Planis in 1972. Since there was no such book on hand, it was impossible to publish the relevant exercises together. This task had to be completed by the para-orthodoxy teachers themselves.
