Jacob Van Eyck
Jacob van Eyck ( , ; 26 March 1657) was a Dutch nobleman and blind musician. He was one of the best-known musicians of the Dutch Golden Age, working as a carillon player and technician, an organist, a recorder virtuoso, and a composer. He was an expert in bell casting and tuning, and taught Pieter and François Hemony how to tune a carillon. Van Eyck is credited with developing the modern carillon together with the brothers in 1644, when they cast the first tuned carillon in Zutphen. He is also known for his collection of 143 melodies for recorder, , the largest work for a solo wind instrument in European history. Biography Early life Jacob van Eyck was born in 1589 or 1590 into a noble family probably in the small town of Heusden. Born blind, he lived with his mother and father well into adulthood. Van Eyck became involved as a player and technician of village's carillon by 1619. He met with several craftsmen and the city organist to discuss changes and improvement ...

Van Eyck
Van Eyck or Van Eijk () is a Dutch toponymic surname. ''Eijck'', ''Eyck'', ''Eyk'' and ''Eijk'' are all archaic spellings of modern Dutch ("oak") and the surname literally translates as "from/of oak". However, in most cases, the family name refers to an origin in Maaseik. This city on the Meuse, now in Belgium on the border with the Netherlands, was originally simply known as ''Eike'' (with many spellings) and from the 13th century as Old Eyck and New Eyck. Names with a particle, like ''Van der Eijk'' are more likely to refer directly to the tree. at the Database of Surnames in The Netherlands. People with this surname include: Renaissance family of painters The important |
Dutch Nobility
The Dutch nobility is a small elite social class constisting of individuals or families recognized as noble, and with or without a title of nobility in the Kingdom of the Netherlands. The existence of nobility was established in the Constitution of the Netherlands of 1814. Those who belong to the nobility were entitled to certain privileges, in particular to take a seat in the "Ridderschap", a former executive and legislative assembly at the regional or provincial level, and herewith the power to select members for the States-Provincial. With the constitutional reform of 1848, all these privileges were abolished and the nobles lost their constitutional roles. Since then, the only privileges that the Dutch nobility still enjoy are the legal use of titles and the grant of coats of arms by royal decree. The nobility are currently regulated by the Nobility Act, passed into law on 1 August 1994, and is overseen by the , an official state institution of the Kingdom of the Netherlands ...

René Descartes
René Descartes ( or ; ; Latinized: Renatus Cartesius; 31 March 1596 – 11 February 1650) was a French philosopher, scientist, and mathematician, widely considered a seminal figure in the emergence of modern philosophy and science. Mathematics was central to his method of inquiry, and he connected the previously separate fields of geometry and algebra into analytic geometry. Descartes spent much of his working life in the Dutch Republic, initially serving the Dutch States Army, later becoming a central intellectual of the Dutch Golden Age. Although he served a Protestant state and was later counted as a deist by critics, Descartes considered himself a devout Catholic. Many elements of Descartes' philosophy have precedents in late Aristotelianism, the revived Stoicism of the 16th century, or in earlier philosophers like Augustine. In his natural philosophy, he differed from the schools on two major points: first, he rejected the splitting of corporeal substance into mat ...

Resonance
Resonance describes the phenomenon of increased amplitude that occurs when the frequency of an applied periodic force (or a Fourier component of it) is equal or close to a natural frequency of the system on which it acts. When an oscillating force is applied at a resonant frequency of a dynamic system, the system will oscillate at a higher amplitude than when the same force is applied at other, non-resonant frequencies. Frequencies at which the response amplitude is a relative maximum are also known as resonant frequencies or resonance frequencies of the system. Small periodic forces that are near a resonant frequency of the system have the ability to produce large amplitude oscillations in the system due to the storage of vibrational energy. Resonance phenomena occur with all types of vibrations or waves: there is mechanical resonance, orbital resonance, acoustic resonance, electromagnetic resonance, nuclear magnetic resonance (NMR), electron spin resonance (ESR) and reso ...

Partial (music)
A harmonic series (also overtone series) is the sequence of harmonics, musical tones, or pure tones whose frequency is an integer multiple of a ''fundamental frequency''. Pitched musical instruments are often based on an acoustic resonator such as a string or a column of air, which oscillates at numerous modes simultaneously. At the frequencies of each vibrating mode, waves travel in both directions along the string or air column, reinforcing and canceling each other to form standing waves. Interaction with the surrounding air causes audible sound waves, which travel away from the instrument. Because of the typical spacing of the resonances, these frequencies are mostly limited to integer multiples, or harmonics, of the lowest frequency, and such multiples form the harmonic series. The musical pitch of a note is usually perceived as the lowest partial present (the fundamental frequency), which may be the one created by vibration over the full length of the string or air column ...

Mersenne's Laws
Mersenne's laws are laws describing the frequency of oscillation of a stretched string or monochord, useful in musical tuning and musical instrument construction. Overview The equation was first proposed by French mathematician and music theorist Marin Mersenne in his 1636 work ''Harmonie universelle''.Mersenne, Marin (1636)''Harmonie universelle'' Cited in, '' Wolfram.com''. Mersenne's laws govern the construction and operation of string instruments, such as pianos and harps, which must accommodate the total tension force required to keep the strings at the proper pitch. Lower strings are thicker, thus having a greater mass per length. They typically have lower tension. Guitars are a familiar exception to this: string tensions are similar, for playability, so lower string pitch is largely achieved with increased mass per length. Higher-pitched strings typically are thinner, have higher tension, and may be shorter. "This result does not differ substantially from Galileo's, yet ...

Marin Mersenne
Marin Mersenne, OM (also known as Marinus Mersennus or ''le Père'' Mersenne; ; 8 September 1588 – 1 September 1648) was a French polymath whose works touched a wide variety of fields. He is perhaps best known today among mathematicians for Mersenne prime numbers, those which can be written in the form for some integer . He also developed Mersenne's laws, which describe the harmonics of a vibrating string (such as may be found on guitars and pianos), and his seminal work on music theory, ''Harmonie universelle'', for which he is referred to as the "father of acoustics". Mersenne, an ordained Catholic priest, had many contacts in the scientific world and has been called "the center of the world of science and mathematics during the first half of the 1600s" and, because of his ability to make connections between people and ideas, "the post-box of Europe". He was also a member of the Minim religious order and wrote and lectured on theology and philosophy. Life Mersenne was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Domtoren Vanaf De Stadhuisbrug
The Dom Tower (Cathedral Tower, Dutch: ''Domtoren'') of Utrecht is the tallest church tower in the Netherlands, at 112.5 metres (368 feet) in height. It is considered the symbol of Utrecht. The tower was part of St. Martin's Cathedral, also known as the Dom Church, and was built between 1321 and 1382, to a design by John of Hainaut. The cathedral was never fully completed due to lack of money. Since the unfinished nave collapsed in 1674, the Dom tower has been a freestanding tower. The tower stands at the spot where the city of Utrecht originated almost 2,000 years ago. Design and construction The Dom Tower was one of the largest towers constructed in Europe during the fourteenth century, and it was planned to show the power of the church in Utrecht. Its construction led preacher Geert Groote to protest against the vanity of such an immense project, suggesting it was too tall, too expensive and all but aesthetic. The tower consists of two square blocks, topped by a much li ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jacobikerk
The Jacobikerk is a landmark Protestant church in Utrecht, Netherlands. The building is located on the St Jacobsstraat, named for its patron saint St. James the Greater. The church is one of the medieval parish churches of Utrecht, along with the Buurkerk, the Nicolaïkerk and the Geertekerk. Today it is known as the starting place for Dutch pilgrims on their way to Santiago de Compostella along the Way of St. James. The Dutch Confraternity of St. James is located around the corner on the St. Jacobskerkhof. History The current gothic church dates from the end of the 13th century, but was expanded in the 14th and 15th centuries.Church website In 1576-1577 a cannon was installed in the church tower, aimed at Vredenburg (castle) where the Spanish soldiers there were under siege by the Utrecht schutters. Around 1580 the church endured the protestant reformation The Reformation (alternatively named the Protestant Reformation or the European Reformation) was a major mov ...

Sint Janskerk
The Sint Janskerk in Gouda, the Netherlands, is a large Gothic church, known especially for its stained glass windows, for which it has been placed on the list of the top 100 Dutch monuments. History The church is dedicated to John the Baptist, the patron saint of Gouda, and was built during the 15th and 16th centuries. In 1552 a large part of the church burned, including the archives. Most information of the early period is taken from the diaries of Ignatius Walvis. Around 1350 a tower was built (only the lower part remains). In 1485 the foundation was built for the present-day choir. This expansion made the church the longest in the Netherlands, with a length of 123 meters. The stained glass windows were made and installed primarily by the brothers Dirk and Wouter Crabeth I, in the years 1555-1571, and after a short stop for the Protestant Reformation, until 1603. During the Reformation the church was spared, because the city fathers sided with the reigning king Philip II ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bell Tower
A bell tower is a tower that contains one or more bells, or that is designed to hold bells even if it has none. Such a tower commonly serves as part of a Christian church, and will contain church bells, but there are also many secular bell towers, often part of a municipal building, an educational establishment, or a tower built specifically to house a carillon. Church bell towers often incorporate clocks, and secular towers usually do, as a public service. The term campanile (, also , ), deriving from the Italian ''campanile'', which in turn derives from ''campana'', meaning "bell", is synonymous with ''bell tower''; though in English usage campanile tends to be used to refer to a free standing bell tower. A bell tower may also in some traditions be called a belfry, though this term may also refer specifically to the substructure that houses the bells and the ringers rather than the complete tower. The tallest free-standing bell tower in the world, high, is the Mortegliano B ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carillonneur
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 o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
