Andreas Ruckers The Elder
The Ruckers family (variants: Ruckaert, Ruckaerts, Rucqueer, Rueckers, Ruekaerts, Ruijkers, Rukkers, Rycardt) were harpsichord and virginal makers from the Southern Netherlands based in Antwerp in the 16th and 17th century. Their influence stretched well into the 18th century, and to the harpsichord revival of the 20th. The Ruckers family contributed immeasurably to the harpsichord's technical development, pioneering the addition of a second manual; the quality of their instruments is such that the name of Ruckers is as important to early keyboard instruments as that of Stradivarius is to the violin family. In the 18th century, Ruckers instruments were often modified by French makers in a process known as ''ravalement'', to allow for an extended range and other additions. The Ruckers family The family probably originated in Germany. The earliest known member, Hans Ruckers, was from Weissenburg, according to documents from 1530 in the Antwerp city archives, and the similarly name ...

Harpsichord
A harpsichord is a musical instrument played by means of a musical keyboard, keyboard. Depressing a key raises its back end within the instrument, which in turn raises a mechanism with a small plectrum made from quill or plastic that plucks one or more strings. The strings are under tension on a Sound board (music), soundboard, which is mounted in a wooden case; the soundboard amplifies the vibrations from the strings so that the listeners can hear it. Like a pipe organ, a harpsichord may have more than one keyboard Manual (music), manual and even a #Pedal harpsichord, pedal board. Harpsichords may also have Organ stop, stop levers which add or remove additional octaves. Some harpsichords may have a buff stop, which brings a strip of buff leather or other material in contact with the strings, muting their sound to simulate the sound of a plucked lute. The term denotes the whole family of similar plucked-keyboard instruments, including the smaller virginals, virginals#Muselars, m ...

Plague (disease)
Plague is an infectious disease caused by the bacterium '' Yersinia pestis''. Symptoms include fever, weakness and headache. Usually this begins one to seven days after exposure. There are three forms of plague, each affecting a different part of the body and causing associated symptoms. Pneumonic plague infects the lungs, causing shortness of breath, coughing and chest pain; bubonic plague affects the lymph nodes, making them swell; and septicemic plague infects the blood and can cause tissues to turn black and die. The bubonic and septicemic forms are generally spread by flea bites or handling an infected animal, whereas pneumonic plague is generally spread between people through the air via infectious droplets. Diagnosis is typically by finding the bacterium in fluid from a lymph node, blood or sputum. Those at high risk may be vaccinated. Those exposed to a case of pneumonic plague may be treated with preventive medication. If infected, treatment is with antibiotics a ...

Louis Couperin
Louis Couperin (; – 29 August 1661) was a French Baroque composer and performer. He was born in Chaumes-en-Brie and moved to Paris in 1650–1651 with the help of Jacques Champion de Chambonnières. Couperin worked as organist of the Church of St. Gervais in Paris and as musician at the court. He quickly became one of the most prominent Parisian musicians, establishing himself as a harpsichordist, organist, and violist, but his career was cut short by his early death at the age of thirty-five. None of Couperin's music was published during his lifetime, but manuscript copies of some 200 pieces survive, some of them only rediscovered in the mid-20th century. The first historically important member of the Couperin family, Couperin made contributions to the development of both the French organ school and the French harpsichord school. His innovations included composing organ pieces for specific registrations and inventing the genre of the unmeasured prelude for harp ...

Bass (instrument)
Bass ( ) (also called bottom end) describes Pitch (music), tones of low (also called "deep") frequency, pitch (music), pitch and range (music), range from 16 to 250 Hz (C0 to middle C4) and bass instruments that produce tones in the low-pitched range (music), range C2-C4. They belong to different families of musical instrument, instruments and can cover a wide range of musical roles. Since producing low pitches usually requires a long air column or string, and for stringed instruments, a large hollow body, the string and wind bass instruments are usually the largest instruments in their families or instrument classes. Musical role When bass notes are played in a musical ensemble such an orchestra, they are frequently used to provide a counterpoint or counter-melody, in a harmony, harmonic context either to outline or juxtapose the progression of the chord (music), chords, or with Percussion instrument, percussion to underline the rhythm.

Chromatic
Diatonic and chromatic are terms in music theory that are used to characterize scales. The terms are also applied to musical instruments, intervals, chords, notes, musical styles, and kinds of harmony. They are very often used as a pair, especially when applied to contrasting features of the common practice music of the period 1600–1900. These terms may mean different things in different contexts. Very often, ''diatonic'' refers to musical elements derived from the modes and transpositions of the "white note scale" C–D–E–F–G–A–B. In some usages it includes all forms of heptatonic scale that are in common use in Western music (the major, and all forms of the minor). ''Chromatic'' most often refers to structures derived from the chromatic scale in 12-tone equal temperament, which consists of all semitones. Historically, however, it had other senses, referring in Ancient Greek music theory to a particular tuning of the tetrachord, and to a rhythmic notational co ...

Timbre
In music, timbre (), also known as tone color or tone quality (from psychoacoustics), is the perceived sound of a musical note, sound or tone. Timbre distinguishes sounds according to their source, such as choir voices and musical instruments. It also enables listeners to distinguish instruments in the same category (e.g., an oboe and a clarinet, both woodwinds). In simple terms, timbre is what makes a particular musical instrument or human voice have a different sound from another, even when they play or sing the same note. For instance, it is the difference in sound between a guitar and a piano playing the same note at the same volume. Both instruments can sound equally tuned in relation to each other as they play the same note, and while playing at the same amplitude level each instrument will still sound distinctive with its own unique tone color. Musicians distinguish instruments based on their varied timbres, even instruments playing notes at the same pitch and volume ...

Antiphonal
An antiphonary or antiphonal is one of the liturgical books intended for use (i.e. in the liturgical choir), and originally characterized, as its name implies, by the assignment to it principally of the antiphons used in various parts of the Latin liturgical rites. Medieval antiphonaries varied with regional liturgical tradition. In 1570, following the Council of Trent, the Roman Rite antiphonary was declared universal. The Roman Antiphonary (''Antiphonale Romanum'') contains the chants for the canonical hours for the hours of Lauds, Prime, Terce, Sext, None, Vespers and Compline for every day of the year. The ''Vesperale Romanum'' is an excerpt of the Antiphonary containing the chants sung at Vespers. The music for use at the Mass is contained in the Roman Gradual (''Graduale Romanum''), the chants of the ordinary are also edited as an excerpt from the Gradual, the ''Kyriale Romanum''. The ''Antiphonale Romanum'' was substantially revised in 1910–11 in the course of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pitch (music)
Pitch is a perception, perceptual property that allows sounds to be ordered on a frequency-related scale (music), scale, or more commonly, pitch is the quality that makes it possible to judge sounds as "higher" and "lower" in the sense associated with musical melody, melodies. Pitch is a major auditory system, auditory attribute of musical tones, along with duration (music), duration, loudness, and timbre. Pitch may be quantified as a frequency, but pitch is not a purely objective physical property; it is a subjective Psychoacoustics, psychoacoustical attribute of sound. Historically, the study of pitch and pitch perception has been a central problem in psychoacoustics, and has been instrumental in forming and testing theories of sound representation, processing, and perception in the auditory system. Perception Pitch and frequency Pitch is an auditory sensation in which a listener assigns musical tones to relative positions on a musical scale based primarily on their percep ...

Hertz
The hertz (symbol: Hz) is the unit of frequency in the International System of Units (SI), often described as being equivalent to one event (or Cycle per second, cycle) per second. The hertz is an SI derived unit whose formal expression in terms of SI base units is 1/s or s−1, meaning that one hertz is one per second or the Inverse second, reciprocal of one second. It is used only in the case of periodic events. It is named after Heinrich Hertz, Heinrich Rudolf Hertz (1857–1894), the first person to provide conclusive proof of the existence of electromagnetic waves. For high frequencies, the unit is commonly expressed in metric prefix, multiples: kilohertz (kHz), megahertz (MHz), gigahertz (GHz), terahertz (THz). Some of the unit's most common uses are in the description of periodic waveforms and musical tones, particularly those used in radio- and audio-related applications. It is also used to describe the clock speeds at which computers and other electronics are driven. T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Strings (music)
In music, strings are long flexible structures on string instruments that produce sound through vibration. Strings are held under tension so that they can vibrate freely. The pitch (frequency) at which a string will vibrate is primarily related to its vibrating length (also called speaking length), its tension, and its mass per unit of length. A vibrating string produces very little sound by itself. Therefore, most string instruments have a soundboard to amplify the sound. There are two main kinds of strings; plain and wound. "Plain" strings are simply one piece of long cylindrical material, commonly consisted of nylon or gut. "Wound" strings have a central core, with other material being tightly wound around the string . Prior to World War II, strings of many instruments (including violins and guitars) were composed of a material known as catgut, a type of cord made from refined natural fibers of animal intestines. During the mid-twentieth century however, steel and nylo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spinet
A spinet is a smaller type of harpsichord or other keyboard instrument, such as a piano or organ. Harpsichords When the term ''spinet'' is used to designate a harpsichord, typically what is meant is the ''bentside spinet'', described in this section. For other uses, see below. The bentside spinet shares most of its characteristics with the full-size instrument, including action, soundboard, and case construction. What primarily distinguishes the spinet is the angle of its strings: whereas in a full-size harpsichord, the strings are at a 90-degree angle to the keyboard (that is, they are parallel to the player's gaze); and in virginals they are parallel to the keyboard, in a spinet the strings are at an angle of about 30 degrees to the keyboard, going toward the right. The case of a bentside spinet is approximately triangular. The side on the right is usually bent concavely (hence the name of the instrument), curving away from the player toward the right rear corner. The lo ...
