吉他颤音(Tremolo)拨弦-简介

Hi, this is Hub Guitar.

Let's talk about tremolo picking.

This is a very cool and very useful technique for playing groups of fast notes.

What some people may not realize, though, is that this is also one of the most valuable ways to build right-hand picking technique.

When we're talking about picking technique, we're generally thinking about speed, tone, clarity. That kind of thing. And those are a product of the combined efforts of the picking hand and the fretting hand.

Each hand has duties that can be developed independently. The fretting hand can independently develop the ability to clearly articulate fretted notes. You can work on that with slurs, hammer-ons, that kind of thing.

And the picking hand can independently develop picking techniques such as this tremolo technique. It's a very rapid alternate picking technique that's usually done on a single string.

Once we've developed skills in both hands, we can start to work on the skill of coordinating them together. And our maximum output will basically be limited by which hand is weaker.

Many players don't know off the top of their head if it's their left hand or right hand that needs the most work. So getting the left and right hands to a really high level will be a huge bonus when you're trying to develop the coordination to play them together.

I'm going to show you how you can turn any melody into tremolo patterns.

First, let's take a simple melody.

Now, let's play that same melody with eighth-note tremolo. That means no note can be longer than an eighth note; all bigger notes are broken down into multiple eighth notes.

Now let's do a 16th-note tremolo. All notes will be broken down into sixteenth notes.

Of course, you can keep going to 32nd notes and beyond, if you've got the picking speed.

I think you'll find if you practice your right-hand tremolo, you'll be able to build a lot of speed in the picking hand, and ultimately take more control of the instrument.


什么是颤音(Tremolo)拨弦?

吉他颤音(tremolo)可以用两种方法达到。

本课:颤音拨弦

首先就是重复弹拨一个音符的拨弦模式,这也是本课的重点,这个技巧中要不断重复同一个音符,不论是古典吉他还是电子吉他,用拨片还是用手指都能做到。.

其他相关课程:Volume Swelling

这一个是一个音符甚至是一个和弦的音量重复向上或向下震动。这一般要配合一个音量踏板或者是拨弦的小手指转电吉他的动音量旋钮;弹奏音符后前后拨动旋钮以制造出一种震动的音效。这个就叫做Volume Swell。但这节课我们主要集中在拨弦技巧上。

将任何旋律转为颤音

颤音可以被应用在任何一段音乐,你只要挑选一个音符重复就可以了。重复弹拨可以形成一种很长很长的音符的音效—而且也能增加它的持久力。在拉丁音乐中,你会经常听到这种音效,还有就是“surf rock”和重金属里。

让我们从这段很简单的旋律开始:

颤音例子1(Basic Melody

注意当我们弹奏这段旋律的时候,有一些音符“消失”地较早。最有一个音,第五品的“C”无法很清晰的延续两拍;而且它几乎是马上就削弱的。我们可以通过重复同个音来把这些音符延长长度。让我们先把每个音符切分为八分音符开始。

颤音例子2(八分音符颤音

注意现在标准的旋律乐谱有个奇怪的“破折号”穿过符干。这个标记意味者把这个音符分为八分音符(一个破折号意味变成八分音符,等于是一根符头。

另外还有就是旋律听上去是很相似的。你的耳朵可能会把重复的音听成一个单音一样。

颤音例子 3(十六分音符颤音)

最后一个例子把音符继续分为十六分音符。这样的结果是这个例子变成颤音更好的示例。我们现在可以听到快速重复音符的效果了。

尝试弹奏这个旋律的所有变形,确保这样的节奏不用变慢持续到十六分音符。

有趣的事实

有一些吉他配有“摇把(whammy bar)”,也叫作“trem”或“tremolo bar”,但其实这是误写,因为用设备制造出的音效完全不是颤音,而是vibrato。

颤音练习

  1. 配合节拍器弹奏十六分音符的颤音,并且尝试慢慢加速。
  2. 用颤音弹奏三度大调音阶,“E” 弦的上下行。
  3. 只用颤音拨弦来即兴演奏。
