Learning to play the unusual nose flute took some trial and error, but once I figured it out, I wanted to share a simple tutorial to help you do the same. By the end of the video, you'll be able to make a whistling sound using just your nose. To play, press the instrument against your nose, cover the hole with your mouth, and exhale through your nose. If no sound comes out, try adjusting your mouth's position slowly until you get it. Once you do, you can shape your mouth differently to create various pitches and tones.
