问题核心:
1. 第七级音不等于导音,导音英文中叫subsemitone,semitone即半音。
2.导音跟主音差一个半音。
3.导音具有强的主音导向性(with a strong affinity for and leading melodically to the tonic)。
3.当第七级音与主音差一个全音时,称为下主音subtonic。
维基百科(英文):
http://en.wikipedia.org/wiki/Leading-tone
截取俩小段,全文点上面链接,
In music theory, a leading-note导音 (also subsemitone, and called the leading-tone in the US) is a note or pitch which resolves or "leads" to a note one semitone半音 higher or lower, being a lower and upper leading-tone, respectively.
As a diatonic function the leading-note is the seventh scale degree of any diatonic scale when the distance between it and the tonic is a single semitone. In diatonic scales where there is a whole tone全音 between the seventh scale degree and the tonic, such as the Mixolydian mode, the seventh degree is called instead, the subtonic(下主音).
之所以发这个帖子,主要是看到很多人把这两个混为一谈,通过维基百科学习,我觉得版友大狮子说的很有道理,导音的“导”是从音乐倾向性来划分的音,跟音级还是要区分开。同理,属,下属,中,应该也差不多。 |
