Humming
A hum ( /hʌm/ ) Latin: murmur, The sound of giraffes humming () 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. H ...

Hummingbird
Hummingbirds are birds native to the Americas and comprise the Family (biology), biological family Trochilidae. With approximately 366 species and 113 genus, genera, they occur from Alaska to Tierra del Fuego, but most species are found in Central America, Central and South America. As of 2024, 21 hummingbird species are listed as Endangered species, endangered or critically endangered, with numerous species declining in population. Hummingbirds have varied specialized characteristics to enable rapid, maneuverable flight: exceptional metabolism, metabolic capacity, adaptations to high altitude, sensitive visual and communication abilities, and long-distance migration in some species. Among all birds, male hummingbirds have the widest diversity of plumage color, particularly in blues, greens, and purples. Hummingbirds are the smallest mature birds, measuring in length. The smallest is the bee hummingbird, which weighs less than , and the largest is the giant hummingbird, weig ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ramphodon Naevius With Flower
The saw-billed hermit (''Ramphodon naevius'') is a hummingbird in the family Trochilidae. It is endemic to Brazil. Taxonomy and systematics The saw-billed hermit is placed in the hermit subfamily Phaethornithinae, but among these birds, it is the species most similar to the typical hummingbirds, Trochilinae.Hinkelmann, C. and G.

The Hum
The Hum is persistent and invasive low-frequency humming, rumbling, or droning noise audible to many but not all people. Hums have been reported in many countries, 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 (hertz), was found to only be heard during cool weather with a light breeze, and often early in the morning. These noises were often con ...

Singing Techniques
Singing is the art of creating music with the voice. It is the oldest form of musical expression, and the human voice can be considered the first musical instrument. The definition of singing varies across sources. Some sources define singing as the act of creating musical sounds with the voice. Other common definitions include "the utterance of words or sounds in tuneful succession" or "the production of musical tones by means of the human voice". A person whose profession is singing is called a singer or a vocalist (in jazz or popular music). Singers perform music (arias, recitatives, songs, etc.) that can be sung with or without accompaniment by musical instruments. Singing is often done in an ensemble of musicians, such as a choir. Singers may perform as soloists or accompanied by anything from a single instrument (as in art songs or some jazz styles) up to a symphony orchestra or big band. Many styles of singing exist throughout the world. Singing can be formal or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kazoo
The kazoo is a 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'' (itself a membranophone), one of a class of instruments that modify the player's voice by way of a vibrating membrane of goldbeater's skin or material with similar characteristics. There is a smaller version of the kazoo, known as a humazoo. Playing A kazoo player hums, rather than blows, into the wider 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 specific syllables such as ''doo'', ''too'', ''who'', or v''rrrr'' into ...

Music Therapy
Music therapy, an allied health profession, "is the clinical and evidence-based use of music interventions to accomplish individualized goals within a therapeutic relationship by a credentialed professional who has completed an approved music therapy program." It is also a vocation, involving a deep commitment to music and the desire to use it as a medium to help others. Although music therapy has only been established as a profession relatively recently, the connection between music and therapy is not new. Music therapy is a broad field. Music therapists use music-based experiences to address client needs in one or more domains of human functioning: cognitive, academic, emotional/psychological; behavioral; communication; social; physiological (sensory, motor, pain, neurological and other physical systems), spiritual, aesthetics. Music experiences are strategically designed to use the elements of music for therapeutic effects, including melody, harmony, key, mode, meter, rhythm, ...

No Audible Release
A stop consonant with no audible release, also known as an unreleased stop, checked stop or an applosive, is a plosive with no release burst: no audible indication of the end of its occlusion (hold). In the International Phonetic Alphabet, lack of an audible release is denoted with an upper-right corner diacritic () after the consonant letter, as in: , , . Audibly released stops, on the other hand, are not normally indicated. If a final stop is aspirated, the aspiration diacritic is sufficient to indicate the release. Otherwise, the "unaspirated" diacritic of the Extended IPA may be employed for this: ''apt'' . English In most dialects of English, the first stop of a cluster has no audible release, as in ''apt'' , ''doctor'' , or ''logged on'' . Although such sounds are frequently described as "unreleased", the reality is that since the two consonants overlap, the release of the former takes place during the hold of the latter, masking the former's release and making it inaud ...

Contact Calls
Contact calls are seemingly haphazard sounds made by many social animals (such as a chicken's cluck). Contact calls are unlike other calls (such as alarm calls) in that they are not usually widely used, conspicuous calls, but rather short exclamations that differ between individuals. Often, the message that the call is meant to convey is specific to the individual or group's activity, such as informing other members of the group about one's location while foraging for food. Some social animal species communicate the signal of potential danger by stopping contact calls, without the use of alarm calls. Charles Darwin wrote about this in relation to wild horse and cattle. Humming as contact calls Joseph Jordania suggested that human humming could have played a function of contact calls in early human ancestors. According to his suggestion, humans find it distressing to be in full silence (which is a sign of danger for them), and this is why humans who are alone sometimes hum, whistle, t ...

Charles Darwin
Charles Robert Darwin ( ; 12 February 1809 – 19 April 1882) was an English Natural history#Before 1900, naturalist, geologist, and biologist, widely known for his contributions to evolutionary biology. His proposition that all species of life have descended from a Common descent, common ancestor is now generally accepted and considered a fundamental scientific concept. In a joint presentation with Alfred Russel Wallace, he introduced his scientific theory that this Phylogenetics, branching pattern of evolution resulted from a process he called natural selection, in which the struggle for existence has a similar effect to the artificial selection involved in selective breeding.. Darwin has been described as one of the most influential figures in human history and was honoured by Burials and memorials in Westminster Abbey, burial in Westminster Abbey. Darwin's early interest in nature led him to neglect his medical education at the University of Edinburgh Medical Schoo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Monophony
In music, monophony is the simplest of texture (music), musical textures, consisting of a melody (or "tune"), typically sung by a single singer or played by a single instrument player (e.g., a flute player) without accompaniment, accompanying harmony or chord (music), chords. Many folk songs and traditional songs are monophonic. A melody is also considered to be monophonic if a group of singers (e.g., a choir) sings the same melody together at the unison (exactly the same pitch) or with the same melody notes duplicated at the octave (such as when men and women sing together). If an entire melody is played by two or more instruments or sung by a choir with a fixed interval, such as a perfect fifth, it is also said to be monophony (or "monophonic"). The musical texture of a song or musical piece is determined by assessing whether varying components are used, such as an accompaniment part or polyphonic melody lines (two or more independent lines). In the Early Middle Ages, the earli ... [...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 frequency, 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, allowing some to even hear ultrasounds. Definition Sound is defined as "(a) Oscillation in pressure, stress, particle displacement, particle velocity, etc., propagated in a medium with internal forces (e.g., elastic or viscous), or the superposition of such propagated oscillation.
