Abstract
A wind instrument that can be used to replicate the calls of birds and animals particularly including the common loon. An instrument having the type of mouthpiece used on a recorder and an elongate body having a bore has an baffle within the bore that closes only a portion of the bore. With the baffle at at least one location in the bore, significant changes can be made in the pitch of the sound being made to replicate calls without movement of the baffle along the bore. The baffle can be fixed and the instrument used to replicate the wail of the common loon, or can be movable so that all of the primary calls of the common loon can be replicated.
Claims15
A wind instrument for replicating the calls of birds or animals, said instrument comprising:
- an elongate body having an outer surface, an inner surface defining a bore having an axis and opposite axially spaced inlet and outlet ends;
- a mouthpiece at the inlet end of the body, said mouthpiece having a through windway smaller than said bore and having an inlet at the end of the mouthpiece opposite the bore and an outlet communicating with the bore at the inlet end of the bore adjacent the inner surface of the body;
- said body having at least one window surface defining a window through said body between said outer and inner surfaces and aligned with the outlet of said windway, said window surface intersecting said inner surface to define a sharp edge at the side of the window opposite the mouthpiece so that air blown through the windway into the bore and the window will produce sound;
- and
- a baffle within said bore closing between 87 to 97 percent of the cross sectional area of said bore and being up to 0.83 inch or 2.11 centimeters long axially along said body, said baffle being movable axially along said bore between inner and outer positions relative to said mouthpiece, and said instrument including an elongate rod smaller in cross sectional area than said baffle having an attached end attached to said baffle and an opposite outer end, said elongate rod projecting from said baffle through the outlet end of said bore, so that with said baffle moved through at least one location in the bore, significant changes can be made in the pitch of the sound being made by blowing into the instrument with a generally steady air pressure to replicate the call.
A wind instrument for replicating the calls of birds or animals, said instrument comprising:
- an elongate body having an outer surface, an inner surface defining a bore having an axis and opposite axially spaced inlet and outlet ends;
- a mouthpiece at the inlet end of the body, said mouthpiece having a through windway smaller than said bore and having an inlet at the end of the mouthpiece opposite the bore and an outlet communicating with the bore at the inlet end of the bore adjacent the inner surface of the body;
- said body having at least one window surface defining a window through said body between said outer and inner surfaces and aligned with the outlet of said windway, said window surface intersecting said inner surface to define a sharp edge at the side of the window opposite the mouthpiece so that air blown through the windway into the bore and the window will produce sound;
- and
- a baffle within said bore closing between 87 to 97 percent of the cross sectional area of said bore and being up to 0.83 inch or 2.11 centimeters long axially along said body, said baffle being fixed at a distance from said edge that affords significant changing of the pitch of the sound being made in response to changing air pressure blown through the instrument to replicate the call.
