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。 |
