The pitch of a vessel flute is affected by how hard the player blows. Fippleless flutes are called edge-blown flutes. Others rely on the player's lips to direct the air against the edge, like a concert flute. Some vessel flutes have a fipple to direct the air onto the labium edge, like a recorder. The opening at which this occurs is called the voicing. The airstream alternates quickly between the inner and outer side of the edge. Sound is generated by oscillations in an airstream passing an edge, just as in other flutes. Just as in a fipple flute, the airstream alternates quickly between the inner and outer side of the labium another diagram, with fipple. In this case, the labium is the edge of the far side of the hole. These are sounded by blowing across a hole, just like blowing across the opening of an empty bottle. As a result, vessel flutes have a distinctive overtoneless sound.Īir pressure oscillating in the body of a vessel flute with no fipple. Most resonators also amplify more overtones. Ī Helmholtz resonator is unusually selective in amplifying only one frequency. Multi-note vessel flutes include the ocarina. This is unlike the resonance of a tube or cone of air, where air moves back and forth along the tube, with pressure increasing in part of the tube while it decreases in another.īlowing across the opening of empty bottle produces a basic edge-blown vessel flute. The air in the body of a vessel flute resonates as one, with air moving alternately in and out of the vessel, and the pressure inside the vessel increasing and decreasing. Vessel flutes have more spherical hollow bodies. Most flutes have cylindrical or conical bore (examples: concert flute, shawm). The body is vessel-shaped, not tube- or cone-shaped that is, the far end is closed. Blowing across the opening of empty bottle produces a basic edge-blown vessel flute.Ī vessel flute is a type of flute with a body which acts as a Helmholtz resonator.
