闷音技巧
Let's talk about the palm muting technique.
So this can give your playing a bit more of an aggressive sound. You take your picking hand and rest it very lightly on the strings, right down here at the edge.
It's very important that you position your picking hand correctly. You can't just touch the strings anywhere. The point that you should touch them is actually all the way at the very end. It's also important that you should make only very light contact with the strings.You don't wanna push down or apply any pressure.
We're going to do a couple of quick examples, and that should give you an idea of how you can use this technique.
First, let's try some chords. It's common to mute chords, especially low-note chords like power chords, and give them a bit more of an aggressive sound. I'm going to play a power chord progression of A5, D5, E5, A5.
You can also use this to play a bass line, or some kind of melodic idea.
So give palm muting a shot and see if you can find a use for it in your own playing.
什么是 Palm Muting（制音）？
Palm muting是当你使用 picking hand（弹拨琴弦的手）闷住琴弦的音的技巧，由于制音技巧下音色加重并且有冲击力，所以经常被使用在重力和弦中。另外，它在弹拨旋律的时候也很有用，因为被制音的琴弦震动幅度变小所产生的特殊的效果给人带来速度感。
首先，让我们用power chords（重力和弦）弹拨一个简单的和弦。
Palm Muting Example #1
通过把 picking hand 的手掌外侧边缘轻轻的贴在需要拨动的琴弦上，可以得到更加有力清晰的效果。注意，一定要将手掌侧面很轻的贴在琴弦上，另外，手与琴弦的接触点也很重要：手掌侧面要贴在琴弦的最末端，也就是 ball-end（琴弦尾端的小球）把琴弦穿过琴桥的地方。
现在让我们来试着用这个技巧弹奏一些基本的 scalar patterns，感受它们在 lead passages里的运用。
