At first, I bought the flute through the association. For some reason, I got a C key, but it's still not easy for beginners to play ... because I have higher requirements for mastering tunes and breath. Later, when I was playing at home, I accidentally broke it ... so I went to the musical instrument store and bought a D key, which may be more useful (but it's ok for me, maybe I studied saxophone for two years in primary school ...).
Xian Jian and Gu Jian's songs are low and high. It is still difficult to complete all the tunes with one flute, but at first I personally suggested buying D key. Well, I feel that going to a musical instrument store is more reliable.
In addition, in fact, many songs have a long aftertaste because of the sounds of various musical instruments (such as erhu and piano). ) is an organic whole, it is difficult to reproduce that artistic conception by flute alone. However, no matter what the result is, you have to try something you like and you won't regret it later.
