It's best to buy a guitar self-study march pass, which is very detailed and easy to understand, and is suitable for beginners and China scholars. In addition, the introduction and improvement of guitar self-study is also good, and 20 lessons of guitar self-study can also be done. But I still recommend you to buy a guitar self-study March pass, which is the best guitar book. In addition, be sure to watch the video. Combining books with videos will make great progress. Video depends on Liu Tianli. I wonder if I can help you. I wish you early success.
