Clavecin électrique
The clavecin électrique (or clavessin électrique) was a musical instrument invented in 1759 by Jean-Baptiste Thillaie Delaborde, a French Jesuit priest. It is the earliest surviving electric-powered musical instrument, antedated only by the Denis d'or, which is only known from written accounts. Delaborde described the instrument in his 1761 publication, ''Le clavessin électrique''. The mechanism was based on a contemporary warning-bell device, and the instrument was essentially an electric carillon. A number of bells, two for each pitch, hang from iron bars along with their clappers (one for each pair). A globe generator charged the prime conductor and the iron bars. The musician pressed a key and one of the bells of the corresponding pair was grounded, cut off from the charge source. The clapper then oscillated between the grounded and the charged bells, producing the desired tone. The somewhat inappropriate choice of the instrument's name was defended by Delaborde, who ...

Musical Instrument
A musical instrument is a device created or adapted to make musical sounds. In principle, any object that produces sound can be considered a musical instrument—it is through purpose that the object becomes a musical instrument. A person who plays a musical instrument is known as an instrumentalist. The history of musical instruments dates to the beginnings of human culture. Early musical instruments may have been used for rituals, such as a horn to signal success on the hunt, or a drum in a religious ceremony. Cultures eventually developed composition and performance of melodies for entertainment. Musical instruments evolved in step with changing applications and technologies. The date and origin of the first device considered a musical instrument is disputed. The oldest object that some scholars refer to as a musical instrument, a simple flute, dates back as far as 50,000 - 60,000 years. Some consensus dates early flutes to about 40,000 years ago. However, most historians be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jean-Baptiste Thillaie Delaborde
Jean-Baptiste Thillais Delaborde (''De Laborde'', ''De La Borde'', also ''Thillais'' and ''Thillaès'') (9 June 1730 – late January 1777) was a French physical scientist, mathematician and Jesuit priest. He was born in Nevers and began his novitiate in the Society of Jesus on 26 September 1745. Around 1755 he was teaching rhetoric in Amiens. He passed the third year of his novitiate in 1762 at Rouen. He spent a number of years in Poznań, then moved to La Collancelle where he served as a priest until his death. He was the author of the book titled ' (Paris, 1761) in which he described the second earliest electric musical instrument—the clavecin électrique. Delaborde built a working model of his innovative instrument and organized performances, however, even though the press was sympathetic to the clavecin électrique, it was never developed further and was soon forgotten. The original model built by Delaborde survives and is kept at the Bibliothèque nationale in Paris ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
French People
The French people (french: Français) are an ethnic group and nation primarily located in Western Europe that share a common French culture, history, and language, identified with the country of France. The French people, especially the native speakers of langues d'oïl from northern and central France, are primarily the descendants of Gauls (including the Belgae) and Romans (or Gallo-Romans, western European Celtic and Italic peoples), as well as Germanic peoples such as the Franks, the Visigoths, the Suebi and the Burgundians who settled in Gaul from east of the Rhine after the fall of the Roman Empire, as well as various later waves of lower-level irregular migration that have continued to the present day. The Norse also settled in Normandy in the 10th century and contributed significantly to the ancestry of the Normans. Furthermore, regional ethnic minorities also exist within France that have distinct lineages, languages and cultures such as Bretons in Brittany, Occi ...

Electricity
Electricity is the set of physical phenomena associated with the presence and motion of matter that has a property of electric charge. Electricity is related to magnetism, both being part of the phenomenon of electromagnetism, as described by Maxwell's equations. Various common phenomena are related to electricity, including lightning, static electricity, electric heating, electric discharges and many others. The presence of an electric charge, which can be either positive or negative, produces an electric field. The movement of electric charges is an electric current and produces a magnetic field. When a charge is placed in a location with a non-zero electric field, a force will act on it. The magnitude of this force is given by Coulomb's law. If the charge moves, the electric field would be doing work on the electric charge. Thus we can speak of electric potential at a certain point in space, which is equal to the work done by an external agent in carrying a unit of p ...

Denis D'or
The Denis d’or (Golden Dionysus) was reportedly the first musical instrument in history that involved electricity. Background The Czech theologian Václav Prokop Diviš, who had his parish in the Moravian town Přímětice near Znojmo, was interested in both music and electricity. He studied the use of electricity first for medical and agrarian purposes, and later for the prevention of thunderstorms. He also tried to apply it to music when he created his own musical instrument that he named "Denis d'or", with the French "Denis" (etymologically going back to "Dionysus"), whose Czech counterpart is "Diviš"—hence the name. The earliest written mention of the Denis d'or dates from 1753, but it is likely that it already existed around 1748. Some sources even date its existence as far back as the year 1730, but this claim is historically untenable and not supported by any available information on Diviš's biography and work. Unfortunately, after Diviš's death in 1765 the unique ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carillon
A carillon ( , ) is a pitched percussion instrument that is played with a keyboard and consists of at least 23 cast-bronze bells. The bells are hung in fixed suspension and tuned in chromatic order so that they can be sounded harmoniously together. They are struck with clappers connected to a keyboard of wooden batons played with the hands and pedals played with the feet. Often housed in bell towers, carillons are usually owned by churches, universities, or municipalities. They can include an automatic system through which the time is announced and simple tunes are played throughout the day. Carillons come in many designs, weights, sizes, and sounds. They are among the world's heaviest instruments, and the heaviest carillon weighs over . Most weigh between . To be considered a carillon, a minimum of 23 bells are needed; otherwise, it is called a chime. Standard-sized instruments have about 50, and the world's largest has 77 bells. The appearance of a carillon depends ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electrical Conductor
In physics and electrical engineering, a conductor is an object or type of material that allows the flow of charge (electric current) in one or more directions. Materials made of metal are common electrical conductors. Electric current is generated by the flow of negatively charged electrons, positively charged holes, and positive or negative ions in some cases. In order for current to flow within a closed electrical circuit, it is not necessary for one charged particle to travel from the component producing the current (the current source) to those consuming it (the loads). Instead, the charged particle simply needs to nudge its neighbor a finite amount, who will nudge ''its'' neighbor, and on and on until a particle is nudged into the consumer, thus powering it. Essentially what is occurring is a long chain of momentum transfer between mobile charge carriers; the Drude model of conduction describes this process more rigorously. This momentum transfer model makes metal an i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bibliothèque Nationale De France
The Bibliothèque nationale de France (, 'National Library of France'; BnF) is the national library of France, located in Paris on two main sites known respectively as ''Richelieu'' and ''François-Mitterrand''.

Paris
Paris () is the capital and most populous city of France, with an estimated population of 2,165,423 residents in 2019 in an area of more than 105 km² (41 sq mi), making it the 30th most densely populated city in the world in 2020. Since the 17th century, Paris has been one of the world's major centres of finance, diplomacy, commerce, fashion, gastronomy, and science. For its leading role in the arts and sciences, as well as its very early system of street lighting, in the 19th century it became known as "the City of Light". Like London, prior to the Second World War, it was also sometimes called the capital of the world. The City of Paris is the centre of the Île-de-France region, or Paris Region, with an estimated population of 12,262,544 in 2019, or about 19% of the population of France, making the region France's primate city.
