导音 meaning in English

leading tone
leading-note

In simple four - part writing this is most evident when the leading tone ( leading note ) follows its naturally tendency to move to the tonic
在简单的四声部写作中，导音遵循其自然属性移向主音时最为明显。
The first degree of the diatonic scale is the tonic , the second the supertonic , the third the mediant , the fourth the subdominant , the fifth the dominant , the sixth the submediant , the seventh the leading tone or leading note
自然音阶的第一级为主音，第二级为上主音，第三级为中音，第四级为下属音，第五级为属音，第六级为下中音，第七级为导音。
Since the leading tone ( leading note ) generally rises to the tonic , doubling the leading note in simple four - part writing would result in doubled leading tone ( note ) followed by a doubled tonic , making the undesirable parallel octaves
导音通常升至主音，四声部写作中重奏导音会导致重奏后的导音后跟随一个重奏后的主音，从而造成并不需要的八度平行。
