Practicing the I V VI IV Progression练习 I-V-vi-IV 和弦进行

For the following exercises, remember to use a metronome to keep in time. Set your metronome to a slower beat and gradually increase the speed as you get more comfortable with these exercises: accuracy over speed always. To begin, just use a simple downstroke for four beats on each chord - don't worry about adding a strumming pattern. And remember, have fun and it's ok if you make mistakes!
对于以下练习，请记住使用节拍器来保持节奏。将节拍器调至较慢的节奏，随着你对这些练习越来越熟悉，逐渐增加速度：准确性总是比速度更重要。开始时，只需在每个和弦上用简单的下击弦法敲击四拍——不要担心添加扫弦模式。并且记住，享受乐趣，犯错也没关系！

Let's start by practicing the I V VI IV chord progression in the key of G. We'll play G D Em C in open position and then with barre chords:
让我们先练习 G 大调的 I-V-VI-IV 和弦进行。我们将以开放位置演奏 G-D-Em-C 和弦，然后使用横按和弦：

Let's play the same progression in the key of C Major and D major.
让我们在 C 大调和 D 大调中演奏相同的和声进行。

Great job!  干得好！
