第六課：第二轉位的三和弦

While composers use root position and first inversion triads freely, second inversion usually occurs in three situations.
（基本音位和第一轉位的三和弦可以自由運用，而第二轉位元經常在三種情況下使用）

Like first inversion, second inversion may be used to smooth out a bass line.
（和第一轉位的運用相同，第二轉位也可以平滑低音線）
Look at this example – notice the movement of the bass line.
（看這個例子，注意它的低音線） |
By using a second inversion V chord, the bass line moves by step and becomes smooth.
（將V變為其第二轉位，低音線就變成了級進方式，更加平滑） |
A second inversion triad used in this fashion is called a passing six-four chord.
（以這種方式使用的三和弦的第二轉位叫通過音第二轉位）

On the chord progression chart, the cadential six-four occurs in between predominants and dominants.
（在和絃進行表中，終止第二轉位位於屬音和前屬音之間）
