Fingering can be taught by yourself ~ you can find a fingering book and start practicing. There are many on the market, so I won't list them one by one. Shao Weimin's flute basic practical course, which I learned. Of course, with the guidance of teachers and their own efforts, you will get twice the result with half the effort.
It is best to have a professional teacher to help you fix your mouth shape.
After learning fingering, I recommend you to buy a book for grading examination, written by Li Guoliang. In fact, most books on the market are similar. The third level is the shepherd boy piccolo, the fourth level is the fishing boat singing, the fifth level is the wild bee flying, the eighth level is the romance in F major, and the tenth level is the great Polish dance music.
Getting started is relatively simple, of course, you have to work hard. You can play some simple songs after learning for a while. Exhale is the lifeblood of flute, and the timbre is actually largely determined by yourself. At this time, it is best to have a teacher to help you, and you can choose an experienced senior. You must practice scales well.
Besides, Yamaha flute is good. You can usually learn it by buying two or three thousand. It is best not to buy flutes below 1500. The material is different from that of 2000, and the timbre will definitely be much worse.
I am from Shanghai, and there is a music bookstore on Fuzhou Road. I wonder if you have ... why don't you look online.
