Chronomètre Of Loulié
The ''chronomètre'' is a precursor of the metronome. It was invented circa 1694 by Étienne Loulié to record the preferred tempo of pieces of music. The Device Musician Étienne Loulié collaborated with mathematician Joseph Sauveur on the education of Philippe II, Duke of Orléans, Philippe, Duke of Chartres, who subsequently asked the pair to work together on a scientific study of acoustics sponsored by the Academy of Sciences, Royal Academy of Science circa 1694. To measure scientifically the number of beats per second caused by different dissonances, they used the "seconds pendulum" invented by Galileo earlier in the century. It doubtlessly was these experiments, on top of his lessons to Chartres, that gave Loulié the idea for his chronomètre, a precursor of the metronome. In his ''Éléments'' (Paris: Ballard, 1696) — which resumes the lessons Loulié had given to Chartres and is dedicated to the prince — Loulié described this invention, complete with an engraving o ...

Metronome
A metronome, from ancient Greek μέτρον (''métron'', "measure") and νομός (nomós, "custom", "melody") is a device that produces an audible click or other sound at a regular interval that can be set by the user, typically in beats per minute (BPM). Metronomes may include synchronized visual motion. Musicians use the device to practise playing to a regular pulse. A kind of metronome was among the inventions of Andalusian polymath Abbas ibn Firnas (810–887). In 1815, German inventor Johann Maelzel patented his mechanical, wind-up metronome as a tool for musicians, under the title "Instrument/Machine for the Improvement of all Musical Performance, called Metronome". In the 20th century, electronic metronomes and software metronomes were invented. Musicians practise with metronomes to improve their timing, especially the ability to stick to a regular tempo. Metronome practice helps internalize a clear sense of timing and tempo. Composers and conductors often use a me ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Étienne Loulié
Étienne Loulié, pronounced .tjɛn lu.lje (1654 – 16 July 1702) was a musician, pedagogue and musical theorist. Life Born into a family of Parisian sword-finishers, Loulié learned both musical practice and musical theory as a choir boy at the Sainte-Chapelle of Paris, under the learned ''maître de musique'' René Ouvrard. In 1673 Loulié left the Chapel and entered the service of Marie de Lorraine, duchesse de Guise, as an instrumentalist (harpsichord, and organ, viol, recorder and perhaps transverse flute as well), performing chiefly in her household ensemble. From 1673 to late 1687, he therefore performed many of the compositions of Marc-Antoine Charpentier, the Guises' household composer. During the late 1680s, Loulié became involved in musical pedagogy and wrote a series of coordinated method books for music teachers. He is credited with introducing the six-fold system of meter classification still taught today. During these same years, he formed a lifelong friendship w ...

Joseph Sauveur
Joseph Sauveur (24 March 1653 – 9 July 1716) was a French mathematician and physicist. He was a professor of mathematics and in 1696 became a member of the French Academy of Sciences. Life Joseph Sauveur was born in La Flèche, the son of a provincial notary. Despite a hearing and speech impairment that kept him totally mute until he was seven, Joseph benefited from a fine education at the Jesuit College of La Flèche. At seventeen, his uncle agreed to finance his studies in philosophy and theology at Paris. Joseph, however, discovered Euclid and turned to anatomy and botany. He soon met Cordemoy, reader to the son of Louis XIV; and Cordemoy soon sang his praises to Bossuet, preceptor to the Dauphin. Despite his handicap, Joseph promptly began teaching mathematics to the Dauphine's pages and also to a number of princes, among them Eugene of Savoy. By 1680, he was something of a pet at court, where he gave anatomy courses to courtiers and calculated for them the odds in the ...

Philippe II, Duke Of Orléans
Philippe II, Duke of Orléans (Philippe Charles; 2 August 1674 – 2 December 1723), was a French prince, soldier, and statesman who served as Regent of the Kingdom of France from 1715 to 1723. He is referred to in French as ''le Régent''. He was the son of Monsieur Philippe I, Duke of Orleans, and Madame Elisabeth Charlotte, Duchess of Orleans. Born at his father's palace at Saint-Cloud, he was known from birth by the title of Duke of Chartres. In 1692, Philippe married his first cousin Françoise Marie de Bourbon, the youngest legitimised daughter (''légitimée de France'') of King Louis XIV and Madame de Montespan. Named regent of France during the minority of Louis XV, his great-nephew and first cousin twice removed, the period of his ''de facto'' rule was known as the Regency (french: la Régence) (1715–1723). The Regency came to an end in February 1723, and the Duke of Orléans died at Versailles in December. Parents In March 1661, Monsieur Phil ...

Academy Of Sciences
An academy of sciences is a type of learned society or academy (as special scientific institution) dedicated to sciences that may or may not be state funded. Some state funded academies are tuned into national or royal (in case of the United Kingdom i.e. Royal Society of London for Improving Natural Knowledge) as a form of honor. The other type of academies are '' Academy of Arts'' or combination of both (e.g., American Academy of Arts and Sciences). ''Academy of Letters'' is another related expression, encompassing literature. In non-English-speaking countries, the range of academic fields of the members of a national Academy of Science often includes scholarly disciplines which would not normally be classed as "science" in English. Many languages use a broad term for systematized learning which includes both natural sciences and social sciences and fields such as literary studies, linguistics, history, or art history. (Often these terms are calques from Latin ''scientia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pendulum
A pendulum is a weight suspended from a pivot so that it can swing freely. When a pendulum is displaced sideways from its resting, equilibrium position, it is subject to a restoring force due to gravity that will accelerate it back toward the equilibrium position. When released, the restoring force acting on the pendulum's mass causes it to oscillate about the equilibrium position, swinging back and forth. The time for one complete cycle, a left swing and a right swing, is called the period. The period depends on the length of the pendulum and also to a slight degree on the amplitude, the width of the pendulum's swing. From the first scientific investigations of the pendulum around 1602 by Galileo Galilei, the regular motion of pendulums was used for timekeeping and was the world's most accurate timekeeping technology until the 1930s. The pendulum clock invented by Christiaan Huygens in 1658 became the world's standard timekeeper, used in homes and offices for 270 years, and ac ...

Galileo
Galileo di Vincenzo Bonaiuti de' Galilei (15 February 1564 – 8 January 1642) was an Italian astronomer, physicist and engineer, sometimes described as a polymath. Commonly referred to as Galileo, his name was pronounced (, ). He was born in the city of Pisa, then part of the Duchy of Florence. Galileo has been called the "father" of observational astronomy, modern physics, the scientific method, and modern science. Galileo studied speed and velocity, gravity and free fall, the principle of relativity, inertia, projectile motion and also worked in applied science and technology, describing the properties of pendulums and "hydrostatic balances". He invented the thermoscope and various military compasses, and used the telescope for scientific observations of celestial objects. His contributions to observational astronomy include telescopic confirmation of the phases of Venus, observation of the four largest satellites of Jupiter, observation of Saturn's rings, and an ...

Henri Foucault
Henri Foucault (? – c. 1719 or 1720) was a French merchant, sheet music publisher (around 1690) and stationer. His shop was located rue Saint-Honoré, under the sign ''À la règle d’or''. He was condemned for publishing and selling ''"Airs de musique"'' of which Jean-Christophe Ballard held the privilege (28 June 1690 judgment). On 15 July 1721, the widow Foucault, then remarried, sold the store and the funds to François Boivin and his uncle, Michel Pignolet de Montéclair, for their music publishing house established the same year. Among others, Foucault published the works of Jean-Baptiste Lully, Marin Marais, Louis-Antoine Dornel and Nicolas Siret.
