Like triads, seventh chords can be inverted by moving the lowest note up an octave.
（與三和弦一樣，七和絃同樣可以把最低音向上移一個八度的方法轉位）

Root position is the same as a triad – the root is the lowest (bass) note.
（七和絃的基礎音位與三和弦相同——根音是最低音） |

Let's invert the chord.
（我們把七和絃轉位）

First inversion is also the same – the third is the lowest note.
（第一轉位） |

Let's invert the chord again.
（再轉位一次）

Second inversion is also the same – the fifth is the lowest note.
（第二轉位與三和弦一樣——五音變成了最低音） |

Let's invert the chord again.
（再轉位一次）

Now, the seventh is the lowest note of the chord.
（現在七音變成了和絃的最低音）

This is called third inversion.
（這就是第三轉位） |

Let's invert the chord one more time.
（我們再把和絃轉位一次）

Notice that the chord returns to root position.
（注意到和絃回到了其基礎音位） |
