Hey guys! A little tip. So my friend, she's a new flute player. Well, we both have the same model except, I've been playing longer. If you are new and you get a new flute, break it in. Play it every day even if only for 10-15 minutes.
A lot of times, people are like, it's not playing right. You have to break it in. I had the same problem. If it's not playing a note right, take it to the shop. It might not be because of the flute though. Make sure you're playing correctly and sitting correctly.
