Bocca Chiusa
A hum is a sound made by producing a wordless tone with the mouth closed, forcing the sound to emerge from the nose. To hum is to produce such a sound, often with a melody. It is also associated with thoughtful absorption, 'hmm'. A hum has a particular timbre (or sound quality), usually a monotone or with slightly varying tones. There are other similar sounds not produced by human singing that are also called hums, as the sound produced by machinery in operation, such as a microwave, or by an insect in flight. The hummingbird was named for the sound that bird makes in flight which sounds like a hum. Mechanics A 'hum' or 'humming' by humans is created by the resonance of air in various parts of passages in the head and throat, in the act of breathing. The 'hum' that a hummingbird creates is also created by resonance: in this case by air resistance against wings in the actions of flying, especially of hovering. Humming in human evolution Joseph Jordania suggested that hum ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sound
In physics, sound is a vibration that propagates as an acoustic wave, through a transmission medium such as a gas, liquid or solid. In human physiology and psychology, sound is the ''reception'' of such waves and their ''perception'' by the brain. Only acoustic waves that have frequencies lying between about 20 Hz and 20 kHz, the audio frequency range, elicit an auditory percept in humans. In air at atmospheric pressure, these represent sound waves with wavelengths of to . Sound waves above 20 kHz are known as ultrasound and are not audible to humans. Sound waves below 20 Hz are known as infrasound. Different animal species have varying hearing ranges. Acoustics Acoustics is the interdisciplinary science that deals with the study of mechanical waves in gasses, liquids, and solids including vibration, sound, ultrasound, and infrasound. A scientist who works in the field of acoustics is an ''acoustician'', while someone working in the field of acoustica ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lullaby
A lullaby (), or cradle song, is a soothing song or piece of music that is usually played for (or sung to) children (for adults see music and sleep). The purposes of lullabies vary. In some societies they are used to pass down cultural knowledge or tradition. In addition, lullabies are often used for the developing of communication skills, indication of emotional intent, maintenance of infants' undivided attention, modulation of infants' arousal, and regulation of behavior. Perhaps one of the most important uses of lullabies is as a sleep aid for infants. As a result, the music is often simple and repetitive. Lullabies can be found in many countries, and have existed since ancient times. Etymology The term 'lullaby' derives from the Middle English ''lullen'' ("to lull") and ''by'' 'e''(in the sense of "near"); it was first recorded circa 1560. A folk etymology derives ''lullaby'' from "Lilith-Abi" (Hebrew for "Lilith, begone"). In the Jewish tradition, Lilith was a demon who ...

Mains Hum
Mains hum, electric hum, cycle hum, or power line hum is a sound associated with alternating current which is twice the frequency of the mains electricity. The fundamental frequency of this sound is usually double that of fundamental 50/60 Hz, ''i.e.''100/120Hz, depending on the local power-line frequency. The sound often has heavy harmonic content above 50/60Hz. Because of the presence of mains current in mains-powered audio equipment as well as ubiquitous AC electromagnetic fields from nearby appliances and wiring, 50/60Hz electrical noise can get into audio systems, and is heard as mains hum from their speakers. Mains hum may also be heard coming from powerful electric power grid equipment such as utility transformers, caused by mechanical vibrations induced by magnetostriction in magnetic core. Onboard aircraft (or spacecraft) the frequency heard is often higher pitched, due to the use of 400 Hz AC power in these settings because 400 Hz transformers are much smaller and ligh ...

The Hum
The Hum is a name often given to widespread reports of a persistent and invasive low-frequency humming, rumbling, or droning noise audible to many but not all people. Hums have been reported all over the world, including the United States, the United Kingdom, Australia and Canada. They are sometimes named according to the locality where the problem has been particularly publicized, such as the "Taos Hum" in New Mexico and the "Windsor Hum" in Ontario. The Hum does not appear to be a single phenomenon. Different causes have been attributed, including local mechanical sources, often from industrial plants, as well as manifestations of tinnitus or other biological auditory effects. Description A 1973 report cites a university study of fifty cases of people complaining about a "low throbbing background noise" that others were unable to hear. The sound, always peaking between 30 and 40 Hz, was found to only be heard during cool weather with a light breeze, and often early in the ...

Kazoo
The kazoo is an American musical instrument that adds a "buzzing" timbral quality to a player's voice when the player vocalizes into it. It is a type of '' mirliton'' (which itself is a membranophone), one of a class of instruments which modifies its player's voice by way of a vibrating membrane of goldbeater's skin or material with similar characteristics. Similar hide-covered vibrating and voice-changing instruments have been used in Africa for hundreds of years. Playing A kazoo player hums, rather than blows, into the bigger and flattened side of the instrument.How to Play Kazoo Kazoos.com, 2013, accessed July 12, 2013 The oscillating air pressure of the hum makes the kazoo's membrane vibrate. The resulting sound varies in pitch and loudness with the player's humming. Players can produce different sounds by singing specifi ...

Yodeling
Yodeling (also jodeling) is a form of singing which involves repeated and rapid changes of pitch between the low-pitch chest register (or "chest voice") and the high-pitch head register or falsetto. The English word ''yodel'' is derived from the German (and originally Austro-Bavarian) word ''jodeln'', meaning "to utter the syllable ''jo''" (pronounced "yo" in English). This vocal technique is used in many cultures worldwide. Recent scientific research concerning yodeling and non-Western cultures has shown that music and speech evolved from a common prosodic precursor. Alpine yodeling was a longtime rural tradition in Europe, and became popular in the 1830s as entertainment in theaters and music halls. In Europe, yodeling is still a major feature of folk music (Volksmusik) from Switzerland, Austria and southern Germany and can be heard in many contemporary folk songs, which are also featured on regular TV broadcasts. In the United States, traveling minstrels were yodeling in th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Overtone Singing
Overtone singing – also known as overtone chanting, harmonic singing, polyphonic overtone singing, and diphonic singing – is a set of singing techniques in which the vocalist manipulates the resonances of the vocal tract, in order to arouse the perception of additional, separate notes beyond the fundamental frequency being produced. From a fundamental pitch, made by the human voice, the belonging harmonic overtones can be selectively amplified by changing the vocal tract, i.e. the dimensions and shape of the resonant cavities of the mouth and human pharynx, the pharynx. This resonant tuning allows singers to create more than one pitch at the same time (the fundamental and one or more selected overtones), while usually generating a single fundamental frequency with their vocal folds. Overtone singing should not be confused with throat singing, in spite of the fact that many throat singing techniques comprise overtone singing. As mentioned, overtone singing involves the ca ...

Field Holler
The field holler or field call is mostly a historical type of vocal work song sung by field slaves in the United States (and later by African American forced laborers accused of violating vagrancy laws) to accompany their tasked work, to communicate usefully, or to vent feelings. It differs from the collective work song in that it was sung solo, though early observers noted that a holler, or ‘cry’, might be echoed by other workers. Though commonly associated with cotton cultivation, the field holler was also sung by levee workers, and field hands in rice and sugar plantations. Field hollers are also known as corn-field hollers, water calls, and whoops. An early description is from 1853 and the first recordings are from the 1930s. The holler is closely related to the call and response of work songs and arhoolies. The Afro-American music form ultimately influenced strands of African American music, such as the blues and thereby rhythm and blues, as well as negro spirituals. The ...

Madama Butterfly
''Madama Butterfly'' (; ''Madame Butterfly'') is an opera in three acts (originally two) by Giacomo Puccini, with an Italian libretto by Luigi Illica and Giuseppe Giacosa. It is based on the short story "Madame Butterfly" (1898) by John Luther Long, which in turn was based on stories told to Long by his sister Jennie Correll and on the semi-autobiographical 1887 French novel '' Madame Chrysanthème'' by Pierre Loti.Chadwick Jenna"The Original Story: John Luther Long and David Belasco" on columbia.edu Long's version was dramatized by David Belasco as the one-act play '' Madame Butterfly: A Tragedy of Japan'', which, after premiering in New York in 1900, moved to London, where Puccini saw it in the summer of that year. The original version of the opera, in two acts, had its premiere on 17 February 1904 at La Scala in Milan. It was poorly received, despite having such notable singers as soprano Rosina Storchio, tenor Giovanni Zenatello and baritone Giuseppe De Luca in lead roles ...

Giacomo Puccini
Giacomo Puccini (Lucca, 22 December 1858Bruxelles, 29 November 1924) was an Italian composer known primarily for his operas. Regarded as the greatest and most successful proponent of Italian opera after Verdi, he was descended from a long line of composers, stemming from the late-Baroque era. Though his early work was firmly rooted in traditional late-19th-century Romantic Italian opera, he later developed his work in the realistic ''verismo'' style, of which he became one of the leading exponents. His most renowned works are ''La bohème'' (1896), ''Tosca'' (1900), '' Madama Butterfly'' (1904), and ''Turandot'' (1924), all of which are among the most frequently performed and recorded of all operas. Family and education Puccini was born Giacomo Antonio Domenico Michele Secondo Maria Puccini in Lucca, Italy, in 1858. He was the sixth of nine children of Michele Puccini (1813–1864) and Albina Magi (1830–1884). The Puccini family was established in Lucca as a local musi ...
