Pitch Pipe
A pitch pipe is a small device (type of tuning Harmonica) used to provide a pitch reference for musicians. Although it may be described as a musical instrument, it is not typically used to play music as such. Origins The earliest pitch pipes were instruments similar to the recorder, but rather than finger holes, they had a plunger like a slide whistle's (also known as a ''swanee whistle'') making it essentially a type of Slide Whistle. The pipe was generally made of wood with a square bore, and the plunger was leather-coated. On this plunger are marked the notes of either the chromatic scale or the diatonic scale, and by setting it to the correct position, the indicated note will be produced when the instrument is blown. Pitch pipes come in all sorts of shapes and sizes. Pitch pipes of this sort were most often used in the 18th and 19th centuries in churches which had no organ to give the opening note of a hymn. They are now quite rare, and hardly ever used for what they we ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
A Cappella
Music performed a cappella ( , , ; ), less commonly spelled acapella in English, is music performed by a singer or a singing group without instrumental accompaniment. The term ''a cappella'' was originally intended to differentiate between Renaissance music, Renaissance polyphony and Baroque (music), Baroque concertato musical styles. In the 19th century, a renewed interest in Renaissance polyphony, coupled with an ignorance of the fact that vocal parts were often doubled by instrumentalists, led to the term coming to mean unaccompanied vocal music. The term is also used, rarely, as a synonym for ''alla breve''. Early history Research suggests that singing and vocables may have been what early humans used to communicate before the invention of language. The earliest piece of sheet music is thought to have originated from times as early as 2000 BC, while the earliest that has survived in its entirety is from the first century AD: a piece from Greece called the Seikilos epi ...

Electronic Tuner
In music, an electronic tuner is a device that detects and displays the pitch of musical notes played on a musical instrument. "Pitch" is the perceived fundamental frequency of a musical note, which is typically measured in hertz. Simple tuners indicate—typically with an analog needle or dial, LEDs, or an LCD screen—whether a pitch is lower, higher, or equal to the desired pitch. Since the early 2010s, software applications can turn a smartphone, tablet, or personal computer into a tuner. More complex and expensive tuners indicate pitch more precisely. Tuners vary in size from units that fit in a pocket to 19" rack-mount units. Instrument technicians and piano tuners typically use more expensive, accurate tuners. The simplest tuners detect and display tuning only for a single pitch—often "A" or "E"—or for a small number of pitches, such as the six used in the standard tuning of a guitar (E,A,D,G,B,E). More complex tuners offer chromatic tuning for all 12 pitches o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tuning Fork
A tuning fork is an acoustic resonator in the form of a two-pronged fork with the prongs ( ''tines'') formed from a U-shaped bar of elastic metal (usually steel). It resonates at a specific constant pitch when set vibrating by striking it against a surface or with an object, and emits a pure musical tone once the high overtones fade out. A tuning fork's pitch depends on the length and mass of the two prongs. They are traditional sources of standard pitch for tuning musical instruments. The tuning fork was invented in 1711 by British musician John Shore, sergeant trumpeter and lutenist to the royal court. Description A tuning fork is a fork-shaped acoustic resonator used in many applications to produce a fixed tone. The main reason for using the fork shape is that, unlike many other types of resonators, it produces a very pure tone, with most of the vibrational energy at the fundamental frequency. The reason for this is that the frequency of the first overtone is about ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Container
A container is any receptacle or enclosure for holding a product used in storage, packaging, and transportation, including shipping. Things kept inside of a container are protected on several sides by being inside of its structure. The term is most frequently applied to devices made from materials that are Durable good, durable and are often partly or completely Stiffness, rigid. A container can also be considered as a basic tool, consisting of any device creating a partially or fully enclosed space that can be used to contain, store, and transport objects or materials. History Humans have used containers for at least 100,000 years, and possibly for millions of years.Clive Gamble, ''Origins and Revolutions: Human Identity in Earliest Prehistory'' (2007), p. 204. The first containers were probably invented for storing food, allowing early humans to preserve more of their food for a longer time, to carry it more easily, and also to protect it from other animals.

Work Hardening
Work hardening, also known as strain hardening, is the process by which a material's load-bearing capacity (strength) increases during plastic (permanent) deformation. This characteristic is what sets ductile materials apart from brittle materials. Work hardening may be desirable, undesirable, or inconsequential, depending on the application. This strengthening occurs because of dislocation movements and dislocation generation within the crystal structure of the material. Many non-brittle metals with a reasonably high melting point as well as several polymers can be strengthened in this fashion. Alloys not amenable to heat treatment, including low-carbon steel, are often work-hardened. Some materials cannot be work-hardened at low temperatures, such as indium, however others can be strengthened only via work hardening, such as pure copper and aluminum. Undesirable work hardening An example of undesirable work hardening is during machining when early passes of a cutter inadver ...

Phonograph Cylinder
Phonograph cylinders (also referred to as Edison cylinders after its creator Thomas Edison) are the earliest commercial medium for Sound recording and reproduction, recording and reproducing sound. Commonly known simply as "records" in their heyday (c. 1896–1916), a name which has been passed on to Phonograph record, their disc-shaped successor, these hollow cylinder, cylindrical objects have an audio recording engraved on the outside surface which can be reproduced when they are played on a mechanical cylinder phonograph. The first cylinders were wrapped with tin foil but the improved version made of wax was created a decade later, after which they were commercialized. In the 1910s, the competing disc record system Format war, triumphed in the marketplace to become the dominant commercial audio medium. Early development In December 1877, Thomas Edison and his team invented the phonograph using a thin sheet of tin foil wrapped around a hand-cranked, grooved metal cylinder. Tin f ...

Gramophone Record
A phonograph record (also known as a gramophone record, especially in British English) or a vinyl record (for later varieties only) is an analog sound storage medium in the form of a flat disc with an inscribed, modulated spiral groove. The groove usually starts near the outside edge and ends near the center of the disc. The stored sound information is made audible by playing the record on a phonograph (or "gramophone", "turntable", or "record player"). Records have been produced in different formats with playing times ranging from a few minutes to around 30 minutes per side. For about half a century, the discs were commonly made from shellac and these records typically ran at a rotational speed of 78 rpm, giving it the nickname "78s" ("seventy-eights"). After the 1940s, "vinyl" records made from polyvinyl chloride (PVC) became standard replacing the old 78s and remain so to this day; they have since been produced in various sizes and speeds, most commonly 7-inch discs pla ...

Ethnomusicology
Ethnomusicology is the multidisciplinary study of music in its cultural context. The discipline investigates social, cognitive, biological, comparative, and other dimensions. Ethnomusicologists study music as a reflection of culture and investigate the act of music-making through various immersive, observational, and analytical approaches. This discipline emerged from comparative musicology, initially focusing on non-Western music, but later expanded to embrace the study of all different music. The practice of ethnomusicology relies on direct engagement and performance, as well as academic work. Fieldwork takes place among those who make the music, engaging local languages and culture as well as music. Ethnomusicologists can become participant observers, learning to perform the music they are studying. Fieldworkers also collect recordings and contextual data. Definition Ethnomusicology combines perspectives from folklore, psychology, cultural anthropology, linguistics, compara ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Solo (music)
In music, a solo () is a musical composition, piece or a section (music), section of a piece played or sung featuring a single performer, who may be performing completely alone or supported by an accompanying instrument such as a piano or Organ (music), organ, a Basso continuo, continuo group (in Baroque music), or the rest of a choir, orchestra, band, or other ensemble. Performing a solo is "to solo", and the performer is known as a ''soloist''. The plural is soli or the anglicisation, anglicised form solos. In some contexts these are interchangeable, but ''soli'' tends to be restricted to classical music, and mostly either the solo performers or the solo passage (music), passages in a single piece. Furthermore, the word ''soli'' can be used to refer to a small number of simultaneous parts assigned to single players in an orchestral composition. In the Baroque concerto grosso, the term for such a group of soloists was ''Concertino (group), concertino''. An instrumental solo is ...

Unison
Unison (stylised as UNISON) is a Great Britain, British trade union. Along with Unite the Union, Unite, Unison is one of the two largest trade unions in the United Kingdom, with over 1.2 million members who work predominantly in public services, including local government, education, health and outsourcing, outsourced services. The union was formed in 1993 when three public sector trade unions, the National Association of Local Government Officers, National and Local Government Officers Association (NALGO), the National Union of Public Employees (NUPE) and the Confederation of Health Service Employees (COHSE) merged. UNISON's current general secretary is Christina McAnea, who replaced Dave Prentis in 2021. Members and organisation Members of UNISON are typically from industries within the public sector and generally cover both full-time and part-time support and administrative staff. The majority of people joining UNISON are workers within sectors such as local government, e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tonic (music)
In music, the tonic is the first scale degree () of the diatonic scale (the first note of a scale) and the tonal center or final resolution tone that is commonly used in the final cadence in tonal (musical key-based) classical music, popular music, and traditional music. In the movable do solfège system, the tonic note is sung as ''do''. More generally, the tonic is the note upon which all other notes of a piece are hierarchically referenced. Scales are named after their tonics: for instance, the tonic of the C major scale is the note C. The triad formed on the tonic note, the tonic chord, is thus the most significant chord in these styles of music. In Roman numeral analysis, the tonic chord is typically symbolized by the Roman numeral "" if it is major and by "" if it is minor. These chords may also appear as seventh chords: in major, as M7, or in minor as 7 or rarely M7: The tonic is distinguished from the root, which is the reference note of a chord, rathe ...
