A hand flute is like a tiny musical instrument that you can play without needing to carry a big flute around. You use your hand to make the sound by blowing into the space between your hand and the side of your mouth. It's a lot like when you blow into your hands to warm them up on a cold day.
To play a hand flute, you first make a cup shape with your hand by bending your fingers slightly and tucking your thumb in beside them. Then, you bring your hand up to your mouth, with the pinkie side pressed against the side of your mouth.
Next, you blow into the space between your hand and your mouth, using a light breath. Make sure not to blow too hard, or the sound won't come out clear. With some practice, you'll start to hear a sound that's similar to a whistle or a flute. You can adjust the pitch of the sound by moving your finger slightly to change the size of the gap between your hand and your mouth.
A hand flute is a fun way to make music anytime and anywhere, without needing a big instrument or a lot of preparation. It's also a great way to practice your breath control and develop your ear for music.
