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 () is a device that produces an audible click or other sound at a uniform interval that can be set by the user, typically in beats per minute (BPM). Metronomes may also include synchronized visual motion, such as a swinging pendulum or a blinking light. Musicians—and others including dancers, athletes, and health professionals—often practise with a metronome to improve their timing, especially the ability to maintain a steady tempo with a regular beat or pulse. Composers and conductors often use numerical metronome markings to communicate their preferred tempos to musicians preparing for a performance. A type of metronome was among the inventions of Andalusian polymath Abbas ibn Firnas (810–887). In 1815, German inventor Johann Maelzel patented a 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Étienne Loulié
Étienne Loulié (; 165416 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 with Sébastien de Brossard ...

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 th ...

Philippe II, Duke Of Orléans
Philippe II, Duke of Orléans (Philippe Charles; 2 August 1674 – 2 December 1723), who was known as the Regent, 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 Philippe I, Duke of Orleans, and Elisabeth Charlotte, Duchess of Orléans. 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 () (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 Philipp ...

Pendulum
A pendulum is a device made of 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. Pendulums were widely used in early mechanical clocks for timekeeping. 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 1656 became the world's standard timekeeper, used in homes and offices for 270 years, and ...

Galileo
Galileo di Vincenzo Bonaiuti de' Galilei (15 February 1564 – 8 January 1642), commonly referred to as Galileo Galilei ( , , ) or mononymously as Galileo, was an Italian astronomer, physicist and engineer, sometimes described as a polymath. 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-era classical 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 the pendulum and " hydrostatic balances". He was one of the earliest Renaissance developers of the thermoscope and the inventor of various military compasses. With an improved telescope he built, he observed the stars of the Milky Way, the phases of Venus, the four largest satellites of Jupiter, Saturn's rings, lunar craters and ...

Jean-Baptiste Lully
Jean-Baptiste Lully ( – 22 March 1687) was a French composer, dancer and instrumentalist of Italian birth, who is considered a master of the French Baroque music style. Best known for his operas, he spent most of his life working in the court of Louis XIV of France and became a French citizenship, subject in 1661. He was a close friend of the playwright Molière, with whom he collaborated on numerous ''comédie-ballets'', including ''L'Amour médecin'', ''George Dandin ou le Mari confondu'', ''Monsieur de Pourceaugnac'', ''Psyché (play), Psyché'' and his best known work, ''Le Bourgeois gentilhomme''. Biography Lully was born on November 28 or 29, 1632, in Florence, Grand Duchy of Tuscany, to Lorenzo Lulli and Caterina Del Sera, a Tuscan family of millers. His general education and his musical training during his youth in Florence remain uncertain, but his adult handwriting suggests that he manipulated a quill pen with ease.

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.
