Bullroarer (music)
Encyclopedia
The bullroarer, rhombus, or turndun, is an ancient ritual musical instrument and a device historically used for communicating over greatly-extended distances. It dates to the Paleolithic period, being found in Ukraine

The bullroarer is sometimes used as a means of demonstrating the Doppler effect

The Doppler effect , named after Austrian physicist Christian Doppler who proposed it in 1842 in Prague, is the change in frequency of a wave for an observer moving relative to the source of the wave. It is commonly heard when a vehicle sounding a siren or horn approaches, passes, and recedes from...

 in sound waves. As the instrument travels around its circular path, its perceived pitch will, to a third party, appear to rise and fall as it moves closer and farther away, respectively.

Design, use, and sound

A bullroarer consists of a weighted aerofoil (a rectangular thin slat of wood

. Typically, the wood slat is trimmed down to a sharp edge around the edges, and serrations along the length of the wooden slat may or may not be used, depending on the cultural traditions of the region in question.
The cord is given a slight initial twist, and the roarer is then swung in a large circle in a horizontal plane, or in a smaller circle in a vertical plane. The aerodynamics

 of the roarer will keep it spinning about its axis even after the initial twist has unwound. The cord winds fully first in one direction and then the other, alternating.

It makes a characteristic roaring vibrato

, the changing speed of the roarer travelling at different parts of its circular path, the rotation of the roarer along its longitudinal axis, and the choice of whether a shorter or longer length of cord is used to spin the bullroarer. By modifying the expansiveness of its circuit and the speed given it, and whether a horizontal plane or a vertical plane is used, the modulation of the sound produced can be controlled, making the coding of information possible. The low frequency component of the sound travels extremely long distances, with the sound being clearly audible over many miles on a quiet night.

Used variously as musical instruments, ritualistic devices, and long range communication devices, many cultures have used bullroarers over at least the last 19,000 years. For example, due to the eerie sound produced, bullroarers were used extensively in late 19th and early 20th Century America in the South, for playing elaborate practical jokes on superstitious country dwellers.

s to ward off evil spirits, bad tidings, and even women and children.

Bullroarers are considered secret men's business by some Aboriginal tribal groups, and hence forbidden for women, children, non-initiated men, or outsiders to even hear. Fison and Howitt documented this in "Kamilaroi and Kurnai" (page198). Anyone caught breaching the imposed secrecy was to be punished by death.

They are used in men's initiation ceremonies and the sound they produced is considered by some Indigenous cultures to represent the sound of the Rainbow Serpent

British Isles

In the British Isles, the bullroarer—under a number of different names and styles—is used chiefly for amusement, although formerly it may have been used for ceremonial purposes. In parts of Scotland it was known as a "thunder-spell" and protected against being struck by lightning. In the novel Gentian Hill, set in Devonshire, Great Britain in the early 19th century, a bullroarer figures as a toy cherished by Sol, an elderly farm labourer, who being non-verbally gifted uses it occasionally to express strong emotion; however, the sound it makes is perceived as being both eerie and unlucky by two other main characters, Stella and Zachary, who have an uneasy sense that ominous spirits of the air ("Them") are being invoked by its whirring whistle.
