周德清在《中原音韵》中曾多次提到“务头”这一曲学名词,但对其具体内涵却始终未加说明,给后世的戏曲研究者们带来了许多的困惑。本文从“务头”的使用情况等方面入手,得出“务头”所谓的“揭起其音,而宛转其调”的概念是指歌曲中高音歌唱并拖腔的高潮部分。 Zhou Deqing repeatedly mentioned “music head” in “Zhongyuan rhyme”, but its specific connotation has never been explained, which brings many confusion to future generations of opera researchers. This article starts with the use of “service head ”, and concludes that the concept of “service head ” so-called “lift its tone, and turn around its tone ” refers to the climax of the song’s treble singing and dragging section.
