Practicing the 12 Bar Blues练习 12 小节布鲁斯

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！

By now, you should be familiar with both open and barre chord fingerings for the I chord, the IV chord, and the V chord in the key of G Major. Let's begin by practicing the basic 12-bar blues in the key of G Major. Play through the progression once using open chords and once using barre chords:
到如今，你应该已经熟悉了 G 大调中 I 和弦、IV 和弦和 V 和弦的开放和弦和横按和弦指法。让我们从练习 G 大调的基本 12 小节布鲁斯开始。先用开放和弦弹奏一次，再用横按和弦弹奏一次这个和弦进行：

Great! Now let's try practicing the 12-bar blues with variations. Just as before, play through the progression once with open chords and once with barre chords. Remember to use your metronome and use a simple downstroke for each beat (four per measure):
太好了！现在让我们尝试练习带有变奏的 12 小节布鲁斯。就像之前一样，先用开放和弦弹奏一次，再用横按和弦弹奏一次。记得使用节拍器，并且每个节拍用简单的下扫（每小节四拍）：

Great job!  干得好！
