Strähle Construction
Strähle's construction is a geometry, geometric method for determining the lengths for a series of string vibration, vibrating strings with uniform diameters and tensions to sound pitch (music), pitches in a specific rational musical temperament, tempered musical tuning. It was first published in the 1743 ''Proceedings of the Royal Swedish Academy of Sciences'' by Swedish master organ (music), organ maker Daniel Stråhle (1700–1746). The Academy's secretary Jacob Faggot appended a miscalculated set of pitches to the article, and these figures were reproduced by Friedrich Wilhelm Marpurg in ''Versuch über die musikalische Temperatur'' in 1776. Several German textbooks published about 1800 reported that the mistake was first identified by Christlieb Benedikt Funk in 1779, but the construction itself appears to have received little notice until the middle of the twentieth century when tuning theorist J. Murray Barbour presented it as a good method for approximating equal temperament ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Abraham Hülphers
Abraham (originally Abram) is the common Hebrew patriarch of the Abrahamic religions, including Judaism, Christianity, and Islam. In Judaism, he is the founding father who began the covenantal relationship between the Jewish people and God; in Christianity, he is the spiritual progenitor of all believers, whether Jewish or non-Jewish; and in Islam, he is a link in the chain of Islamic prophets that begins with Adam and culminates in Muhammad. Abraham is also revered in other Abrahamic religions such as the Baháʼí Faith and the Druze faith. The story of the life of Abraham, as told in the narrative of the Book of Genesis in the Hebrew Bible, revolves around the themes of posterity and land. He is said to have been called by God to leave the house of his father Terah and settle in the land of Canaan, which God now promises to Abraham and his progeny. This promise is subsequently inherited by Isaac, Abraham's son by his wife Sarah, while Isaac's half-brother Ishmael is als ...

Johann Mattheson
Johann Mattheson (28 September 1681 – 17 April 1764) was a German composer, critic, lexicographer and music theorist. His writings on the late Baroque and early Classical period were highly influential, specifically, "his biographical and theoretical works were widely disseminated and served as the source for all subsequent lexicographers and historians". Early life and career Johann Mattheson was born on 28 September 1681 in Hamburg. The son of a prosperous tax collector, Mattheson received a broad liberal education and, aside from general musical training, took lessons in keyboard instruments, violin, composition and singing. By age nine he was singing and playing organ in church and was a member of the chorus of the Hamburg opera. He made his solo debut with the Hamburg opera in 1696 in female roles and, after his voice changed, sang tenor at the opera, conducted rehearsals and composed operas himself. He was cantor at St. Mary's Cathedral, Hamburg from 1718 until increa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 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 ascetical Minim religious order and wrote and lectured on theology and philosophy. Life Mersenne was b ...

Gioseffo Zarlino
Gioseffo Zarlino (31 January or 22 March 1517 – 4 February 1590) was an Italian Music theory, music theorist and composer of the Renaissance music, Renaissance. He made a large contribution to the theory of counterpoint as well as to musical tuning. Life and career Zarlino was born in Chioggia, near Venice. His early education was with the Franciscans, and he later joined the order himself. In 1536 he was a singer at Chioggia Cathedral, and by 1539 he not only became a deacon, but also principal organist. In 1540 he was ordained, and in 1541 went to Venice to study with the famous contrapuntist and ''maestro di cappella'' of San Marco di Venezia, Saint Mark's, Adrian Willaert. In 1565, on the resignation of Cipriano de Rore, Zarlino took over the post of ''maestro di cappella'' of St. Mark's, one of the most prestigious musical positions in Italy, and held it until his death. While ''maestro di cappella'' he taught some of the principal figures of the Venetian School (musi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vincenzo Galilei
Vincenzo Galilei (3 April 1520 – 2 July 1591) was an Italian lutenist, composer, and music theory, music theorist. His children included the astronomer and physicist Galileo Galilei and the lute virtuoso and composer Michelagnolo Galilei. Vincenzo was a figure in the musical life of the late Renaissance and contributed significantly to the musical revolution that demarcates the beginning of the Baroque music, Baroque era. In his study of pitch and string tension, Galilei produced perhaps the first non-linear mathematical description of a natural phenomenon known to history. Some credit him with directing the activity of his son away from pure, abstract mathematics and towards experimentation using mathematical quantitative description of the results, a direction of importance for the history of physics and natural science. Biography He was born in 1520 in Santa Maria a Monte, near Pisa, Republic of Florence, and began studying the lute at an early age. His mother was from San ...

Samuel Klingenstierna
Samuel Klingenstierna (18 August 1698 – 26 October 1765) was a Swedish mathematician and scientist. He started his career as a lawyer but soon moved to natural philosophy. As a student he gave lectures on the then novel mathematical analysis of Newton and Leibniz. Klingenstierna was a professor of geometry at Uppsala University from 1728. In 1750 he moved to physics but retired two years later to become an advisor to the Commander of Artillery. In 1756 he assumed the post of the tutor of the Crown Prince, the future king Gustav III. He was the first to enunciate errors in Newton's theories of refraction, geometrical notes that John Dollond used in his experiments. Later on he was instrumental in the invention of the Achromatic Telescope The achromatic telescope is a refracting telescope that uses an achromatic lens to correct for chromatic aberration. How it works When an image passes through a lens, the light is refracted at different angles for different wavelengths. T ...

Augustin Ehrensvärd
Field Marshal count Augustin Ehrensvärd (25 September 1710 – 4 October 1772) was a Swedish military officer, military architect, artist, creator of the Suomenlinna (Sveaborg) fortress, Svartholm fortress and the Swedish archipelago fleet. He was born in Fullerö Castle, Barkarö and died in the village of Saris, Mynämäki. In 1747, he was chosen by king Frederick I of Sweden to design and construct a maritime fortress near Helsinki in Finland, then a part of the Kingdom of Sweden. Building the fortress of Sveaborg became a life's work for Ehrensvärd, who kept expanding the island fortress until his death in 1772. Ehrensvärd's design was a low-profile bastion-type fortress that would follow the natural contours of the islands and thus remain inconspicuous to enemy fleets. Many of the constructions in Sveaborg are considered to be architectural masterpieces. Augustin Ehrensvärd was also the commander of the Swedish archipelago fleet from 1756 to 1766, and from 1770, unt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
