Hand flute or
Handflute is a sort of
musical instrument made by the hands. It is also called 'Hand ocarina' or 'Hand whistle'. By making a chamber in the hands and blow air between your thumbs into the hands, you will get a sound. There are two different techniques to hold the hands, "cupped hand" technique and "interlock" technique. The pitch depends on how you hold the hands. If you make the volume inside the hands smaller or make the opening larger you will get higher pitch: the principles are the same as for an ocarina or Helmholtz resonator. The best hand flute players in the world have a range between 2.5 to 3 octaves.
