向下拨弦技巧
Let's talk about down picking.
Depending on the player, down picking will tend to have a bit of a different tone than up-picking. And like every picking technique, it will tend to work better for certain patterns than others.
And the first step to unlocking these patterns is to master the picking technique that will help you to discover them. So let's take a look at some downpicking exercises.
First of all, most alternate picking exercises can be played as down-picking. So if you're familiar with the standard alternate picking exercise that goes across all strings in a "1-2-3-4" pattern, you can play that with down picking, too.
You can also play exercises that emphasize moving down across the strings, or staying on the low strings. I'm going to give you couple examples of those. Here is the first exercise. So here is the first exercise, you can repeat them as many times as you like. Here is second exercise. So in addition to those exercise, of course you can make up as many as your own exercise as you like, and try to really explore what situations make strict downpicking seem a little more appealing and what types of patterns and what kind of things can come out of that.
什么是 Downpicking（向下拨弦）？
Downpicking 就是使用向下拨弦弹奏的技巧。它是 alternate picking 的一半。
Downpicking的缺点
Downpicking 的缺点是机械性的低效率。每当你向下拨弦后，你必须再次回到你开始拨弦的位置（除非换弦）。然而，练习 downpicking也是对你有好处的。首先是你可能注意到，分开练习 downpicking 和 up-picking 可以帮助你加强你的 alternate picking（交替式拨弦）技巧。第二，downpicking 会发出和 up-picking 以及 alternate picking不同的音色。最后，好的 picking（拨弦）是下拨，上拨，交替，economy，sweep的结合。单独强化每一环节都能使你更有效掌握。
Downpicking 的使用方法
这个技巧也可以被使用在弹奏一些没有很多音符，但有比较复杂的节奏的乐段，比如有 sixteenth note syncopationSyncopation refers to an emphasis on playing notes in between pulses of the beat, as opposed to playing notes on top of the beat.（十六分切分音符）或者 triplets（三连音）。因为在这种情况下，单单交替式拨弦会更难弹准音符。
用 up-tempo（快节奏的）弹奏这个练习，注意规定自己只用 downstrokes。 尽管很多人可能会用 upstrokes（上拨），但今天我们这里只专注于 down stroke，so stick to it!

本日目标
- 尝试弹奏以及即兴演奏其他的 bassline，并 grooves on最低的两根弦，尽量使用 downstroke。
- 找一些你平时会用 alternate picking 来弹奏的段子，但换用 downstroke。
