My first flute is about $50. When I was praticing, everything just weird, like the note is way off. Then I bought a $500 Yamaha one, which is much better (to me).
But today I was still bad at playing the flute. Because I code 40 hours a day (no).
Apparently, I like music and coding, but somehow coding is more interesting to me.

@skyblond I recommend the electric Ukulele that can tap into your phone. My son, with no apparent musical ability, learned with this and is now quite good. No complaints. :)
This is Mur 
Maybe I need a proper teacher. Since I originally decide to learn the flute by watching youtube videos. Apparently, my neighbors are super disappointed when I keep practicing for months but got no progress. Considering how poor my house's sound insulation is and how loud I play (I don't know how to play quietly, I mean, you can put something on the violin so it generates less noise, but flute? I don't know.)
