Overtone flute

An overtone flute is like a normal flute that you blow into to make a pretty sound, but it can also make other sounds that are like a magic trick! When you play a normal note on the flute, it actually makes other quiet notes at the same time that you can't usually hear because they are so quiet. But with the overtone flute, you can learn to make those quiet notes louder and they sound like a completely different note! It's like having a secret note inside the normal note. It takes a lot of practice and patience to learn how to do it, but it's really cool when you can make those secret notes come out.
