和声走向:为什么和弦的顺序很重要?

Hi. This is Hub Guitar.

We're going to do a quick lesson about harmonic stress. Harmonic stress is the idea that, if you play a group of chords, the order matters. Each chord's relative weight or importance will be affected by the position it takes in the series.

Let's consider a C, Am, D, and G. These chords have the function of I, vi, ii, V.

In a series of four, the harmonic stress can be described as very strong, somewhat weak, somewhat strong, very weak. So the first chord is the heaviest, followed by 3. 2 is lighter, and 4 is the lightest.

So if we take these same four chords and change them around, the strength of each chord will increase or decrease based on its new position in the series. So I'm going to show you an example. Here is I, vi, ii, V.

This concept is often used as a guide when writing chord progressions. For instance a powerful-sounding chord will often be weakened by placement on a weak beat. That evens things out and prevents the chord from overpowering everything else.

So far, each of these chords took up one measure each consisting of four beats. But you can actually find another, deeper harmonic stress by dividing those measures into four beats. For instance, if we take the last measure, which is already the weakest measure, we'll find that the first beat in the last measure is the strongest in that measure, and the last beat in that measure is the weakest. So sometimes a very powerful and dissonant chord would be placed near the last beat of the last measure in a group of four. And that chord will sound very weak.


Harmonic stress就是和弦进行中和弦之间互相的关系,是对音乐感知的重要元素

这是音乐中的metricRefers to the repeating lattice of beats (steady pulses expressed as BPM), and how they are divided into even units called measures.(韵律学)的问题。和弦在一个组合中相对的位置,会影响到我们对它们的感知。就像在心理学中,给测试者一张清单列表的话,他们一定会倾向与记住首项和末项。

harmonic stress还可以被理解为和弦的强弱拍,理解harmonic stress能够帮助你重弹强拍,弱弹弱拍。

看看下面的和弦进行,哪些和弦是强拍?

I vi ii V
Cmaj Amin Dmin Gmaj

从和声的角度来看,很明显I chord是最重要的和弦,尽管你可以说V chord有更强的motion。

会影响到和弦进行中的和弦的强弱拍,还取决于他们的位置。

大多数歌曲都是用common timeAs the name implies, the most common time signature, having four beats per measure. 四四拍,就是每measureThe basic unit of beat grouping in music. Often the grouping is a measure of four beats, also called common time.小节有4拍。


“强 弱 强 弱”

四拍构成一个小节,四个小节构成一个phrase(乐句);在传统音乐重,两段乐句构成一个period(乐段),它是音乐中表现乐曲的最小结构。

任何一组四个和弦,不管它们速度有多快,始终都有强弱拍之分,这由于人们倾向于将和弦分成等长的小组,最常见的还是四拍。看看上面这个和弦进行,会出现这样的情况:

第一拍是最强的,最后一拍是最弱的;第二拍弱,第三排强。由此重复。

“强”或“弱”和音乐演奏和编曲无关;它是关于人们对音乐的感知。听者会潜意识的听到歌曲中的强弱拍,你可以把你想要强调的和弦放在强拍上以增加它的影响力。
