But there are two versions of Fengwei Bamboo in the Moonlight, one in one key (which is what I mean by Grade 3), and the other in C and F. The second half of this version is played in the key of F with the gourd as the cylinder note 1, which makes it a bit more difficult to learn. But in general, both versions are not as difficult as Bamboo House Love Song and Deep in the Bamboo Forest.
If you are a beginner, you should start from the easy to the difficult, and it is recommended that you play the Fengwei Bamboo first.
