2 Pack Flute Blowing Aid Blower Flute Mouthpiece Whistle Nozzle for Beginner Helper Universal Bamboo Flute Easy to Blow Wind Director Wooden Musical Instrument Kids Adults Learning Practice

It took me a bit to figure out. You have to blow in mouth piece. My silly.brain thought it was a lip wrest to help you position. It does help.

Since different notes require slightly different blowing techniques and angles, this wind director is only good for notes 1, 2, and 3. Anything higher or lower progressively gets more "windy" in sound until no sound is produced at notes beyond 5 or bass 6. Playing in the second octave is impossible with this device.

I bought this for my standard flute, and was pleasantly surprised that it worked! I've never been able to make a sound with a flute, so this is a great workaround. Highly recommend!

Quite pleased with my purchase.

Doesn’t fit any of my bamboo flutes at all.
