Although hundreds of different chord progressions are possible, most tend to follow a pattern.
(尽管和弦进行有上百种可能,但它们通常都有一定规律)
In a major key, the goal of any chord progression is the I chord.
(在大调中,所有和弦进行都要回到I和弦)
The rest of the pattern is based around the strongest ways to get to this chord.
(剩下的和弦进行的建立是为了以最强的方式到达这一和弦)
An authentic cadence (V → I) or (viio → I) is the strongest way to approach a I chord.
(正格终止(V → I或viio → I)是到达I的最强方式)
Next, we use circle progressions.
(接下来我们用循环进行)
The strongest way to approach V is a circle progression from ii.
(最强的到达V的和弦进行是ii的循环进行)
The strongest way to approach viio is a circle progression from IV.
(最强的到达viio的和弦进行是IV的循环进行)
The strongest way to approach IV is a circle progression from I; however, since I is already on the chart, we will not repeat it.
(最强的到达IV的和弦进行是I的循环进行,但是I已经在表中了,我们就不重复它了)
A circle progression from vi leads us to ii.
(vi的循环进行是ii)
A circle progression from iii leads us to vi.
(iii的循环进行是vi)
The strongest way to get to iii is a circle progression from viio, which is already on the chart.
(最强的到达iii的和弦进行是viio的循环进行,但是它已经在表中了)
Finally, since I is the main chord of the scale, it can go to any other chord.
(最后,因为I是调性中最主要的和弦,它可以移动到任意一个其他和弦去)
Now that the chart is complete, there are a few terms that you should learn.
(现在表完成了,有几个概念需要学习)
Recall that the term “dominant” means the fifth scale degree. Since the V chord is built on the dominant, it is a dominant chord.
(回想属音是调性中的第五度音,V和弦是建立在属音上的,所以它就是属和弦)
Since viio functions like V (by going to I), it can also be labeled as a dominant.
(viio到I和V到I的作用是一样的,所以它也是属和弦)
Hence, V and viio are dominants.
(那么,V和viio都是属和弦)
Since ii and IV come before V and viio, they are usually labeled as predominants.
(因为ii和IV在V和viio之前,所以它们是前属和弦)
Let's work out a chord progression using the chart. We will start at I.
(我们用这张表来完成一次和弦进行,从I开始)
Next, we can choose any chord. Let's go to vi.
(接下来选择任意和弦,我们选择vi)
Now, we can choose either ii or IV.
(现在,我们可以选择ii或者IV)
Let's go with IV.
(我们选IV)
Now, we can choose either V or viio. Let's go with V.
(现在我们可以选择V或者viio,我们选V)
Finally, V takes us back to I.
(最后从V回到I)
Our finished chord progression is: I→vi→IV→V→I.
(我们完成的和弦进行是I→vi→IV→V→I) | 
The chord progression chart for minor scales is very similar to the major scale chart. There is only one main difference.
(小调的和弦进行与大调的和弦进行很相似,只有一个不同的地方)
The strongest way to approach III is not viio. Instead, it is a circle progression from VII.
(最接近III的不是viio,而是VII的循环进行)
A circle progression from iv to VII completes the chart.
(从iv到VII的循环进行就可以完成这张表)
It should be noted that the charts do not have to be followed strictly. If a progression is not presented, a composer is not banned from using it.
(值得注意的是,表中所示并不是唯一正确的和弦进行,作曲家也可以使用表中没有表示的和弦进行)
