转位 Inversion (music)
(重定向自Double Counterpoint)
转位是指音在音程中的互换,音程中的两个音如果低音向上提高八度,或高音向下移动八度,构成的音程称为转位音程。一个和弦中除根音以外的音作为最低音,则称为转位和弦。
音程转位后相知会变化,大音程转位后会变成小音程,小音程转为大音程,增音程转为减音程,减音程转位增音程,完全音程转位后不变化。
和弦转位,三和弦中三音为低音是第一转位,五音为低音是第二转位,共有两个转位。七和弦有三个转位,以三音为低音是第一转位,五音为低音是第二转位,七音为低音是第三转位。

The melody on the first line starts on A, while the melody on the second line is identical except that it starts on E and when the first melody goes up the second goes down an equal number of diatonic steps, and when the first goes down the second goes up an equal number of steps.](/uploads/202501/09/Inversion_example5224.png)
