A musical instrument capable of producing the sound spectrum associated with a traditional Australian didjeridoo, but in a more compact and portable form. In certain embodiments, an air column follows a tortuous path between a mouthpiece, having an input orifice between about one to about one-and-one-half inches in diameter, and an exit port. The air column is housed within a body having a length. The ratio of length of the air column to the instrument body length is preferably greater than 1.5 to provide a compact instrument. The instrument may be manufactured tuned to a traditional key-scale note, and may include tone holes to play other fundamental notes. In certain embodiments, a vibrating membrane may be provided in sealed relation over one or more through-holes in the body to produce other sounds of which a traditional didjeridoo is incapable.
A musical instrument constructed and arranged to provide a tortuous path air chamber with a first mouth piece at a first end configured to permit an instrumentalist to blow through said mouthpiece in a loose-lipped fashion, whereby to create a drone emulating a didjeridoo, wherein:
A musical instrument constructed and arranged to provide a tortuous path air chamber with a first mouth piece at a first end configured to permit an instrumentalist to blow through said mouthpiece in a loose-lipped fashion, whereby to create a drone emulating a didjeridoo, wherein:
An apparatus having a body with a first length, the apparatus comprising:
A musical instrument with a body having a first length, said body being formed substantially as a hollow box, said box having an internal baffle arrangement defining an air column following a tortuous path having a second length between a mouthpiece and a sound exit port, said first and second lengths producing a compactness factor greater than about one and-one-half, and said mouthpiece providing an input orifice shaped and dimensioned to accommodate the lips of an instrumentalist such that a loose-lipped input sound may be generated.
