Whistles
Whistling without the use of an artificial whistle is achieved by creating a small opening with one's lips, usually after applying moisture (licking one's lips or placing water upon them) and then blowing or sucking air through the space. The air is moderated by the lips, curled tongue, teeth or fingers (placed over the mouth or in various areas between pursed lips) to create turbulence, and the curled tongue acts as a resonant chamber to enhance the resulting sound by acting as a type of Helmholtz resonator. By moving the various parts of the lips, fingers, tongue and epiglottis, one can then manipulate the types of whistles produced. Techniques Pucker whistling is the most common form in much Western music. Typically, the tongue tip is lowered, often placed behind the lower teeth, and pitch altered by varying the position of the tongue. Although varying the degree of pucker will change the pitch of a pucker whistle, expert pucker whistlers will generally only make small var ...

Shepherd's Whistle
A shepherd's whistle is a specialized, modulatable, variable-pitch whistle used to train and transmit commands to working dogs and other animals. Unlike other whistles, they are placed inside the mouth. The pitch is controlled by the placement of the tongue; physically, shepherd's whistles are vessel flutes with the tongue forming one side of the resonating chamber, and controlling its size. Like tin whistles, while simple, they can be used as musical instruments in their own right. Purpose A shepherd's whistle is traditionally used for communicating commands to a sheepdog to aid in herding. They are typically seen used at sheepdog trials, but are also used for other working dogs including gundogs, and for falconry. Shepherd's whistles are used to communicate clearly, and at distances up to , the commands of the owner to their working dog. They produce clear, high-frequency tones of an easily modulated and variable pitch, allowing the shepherd to communicate a variety of comm ...

Whistle
A whistle is an instrument which produces sound from a stream of gas, most commonly air. It may be mouth-operated, or powered by air pressure, steam, or other means. Whistles vary in size from a small slide whistle or nose flute type to a large multi-piped church organ. Whistles have been around since early humans first carved out a gourd or branch and found they could make sound with it. In prehistoric Egypt, small shells were used as whistles. Many present day wind instruments are inheritors of these early whistles. With the rise of more mechanical power, other forms of whistles have been developed. One characteristic of a whistle is that it creates a pure, or nearly pure, tone. The conversion of flow energy to sound comes from an interaction between a solid material and a fluid stream. The forces in some whistles are sufficient to set the solid material in motion. Classic examples are Aeolian tones that result in galloping power lines, or the Tacoma Narrows Bridge (th ...

Whistled Language
Whistled languages use whistling to emulate speech and facilitate communication. A whistled language is a system of whistled communication which allows fluent whistlers to transmit and comprehend a potentially unlimited number of messages over long distances. Whistled languages are different in this respect from the restricted codes sometimes used by herders or animal trainers to transmit simple messages or instructions. Generally, whistled languages emulate the tones or vowel formants of a natural spoken language, as well as aspects of its intonation and prosody, so that trained listeners who speak that language can understand the encoded message. Whistled language is rare compared to spoken language, but it is found in cultures around the world. It is especially common in tone languages where the whistled tones transmit the tones of the syllables (tone melodies of the words). This might be because in tone languages the tone melody carries more of the functional load of co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
