10 Years Old

took a flute lesson in Mizuho city:) I have played the flute for 10 years actually:) Yes, this is my 10-year-old flute. I have played most of pieces that are well known. So I'm trying unknown pieces that are worth practicing. Really hard though. Also it is said that the temporal limitation of practicing the flute is three hours. I know you don't believe me, but it's true! I got tendovaginitis after practicing for 4 hours.
