Organ Console
The pipe organ is played from an area called the console or keydesk, which holds the manuals (keyboards), pedals, and stop controls. In electric-action organs, the console is often movable. This allows for greater flexibility in placement of the console for various activities. Some very large organs, such as the van den Heuvel organ at the Church of St. Eustache in Paris, have more than one console, enabling the organ to be played from several locations depending on the nature of the performance. Controls at the console called stops select which ranks of pipes are used. These controls are generally either draw knobs (or stop knobs), which engage the stops when pulled out from the console; stop tablets (or tilting tablets) which are hinged at their far end; or rocker-tablets, which rock up and down on a central axle. Different combinations of stops change the timbre of the instrument considerably. The selection of stops is called the registration. On modern organs, the regis ...

Manual (music)
The word "manual" is used instead of the word "keyboard" when referring to any hand-operated keyboard on a keyboard instrument that has a Pedal keyboard, pedalboard (a keyboard on which notes are played with the feet), such as an organ; or when referring to one of the keyboards on an instrument that has more than one hand-operated keyboard, such as a two- or three-manual harpsichord. (On instruments that have neither a pedalboard nor more than one hand-operated keyboard, the word "manual" is ''not'' a synonym for "keyboard".) Music written to be played only on the manuals (and not using the pedals) can be designated by the word manualiter (first attested in 1511, but particularly common in the 17th and 18th centuries). Overview Organs and synthesizers can, and usually do, have more than one manual; most home instruments have two manuals, while most larger organs have two or three. Elaborate pipe organs and theater organs can have four or more manuals. The manuals are set into th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crescendo Pedal
A crescendo pedal is a large pedal commonly found on medium-sized and larger pipe organs (as well as digital organs), either partially or fully recessed within the organ console. The crescendo pedal incrementally activates stops as it is pressed forward and removes stops as it is depressed backward. The addition of stops, in order from quietest to loudest, creates the effect of a crescendo (and, likewise, a diminuendo, when the stops are deactivated). In actual use, the operation of the crescendo pedal usually does not move the draw knobs or stop tabs on the console; the stops are electronically activated inside the organ. Often an indicator light or lights will be present on the console to inform the organist of when the crescendo pedal is activated and how far it is engaged. The crescendo pedal is located directly above the pedalboard, to the right of any expression pedals that may be present. The earliest type of automatic crescendo device was the ''Rollschweller'' ( G ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Expression Pedal
An expression pedal is an important control found on many musical instruments including organs, electronic keyboards, and pedal steel guitar. The musician uses the pedal to control different aspects of the sound, commonly volume. Separate expression pedals can often be added to a guitar amplifier or effects unit and used to control many different aspects of the tone. Because the source of power with a pipe organ and electronic organs is not generated by the organist, the volume of these instruments has no relationship with how hard its keys or pedals are struck; i.e., the organ produces the same volume whether the key or pedal is depressed gently or firmly. Moreover, the tone will remain constant in pitch, volume, and timbre until the key or pedal is lifted, at which point the sound stops. The expression pedal gives the organist control over the external source of power, and thus the volume, of the instrument, while leaving the user's hands free. This system of dynamic contro ...

Window Blind
A window blind is a type of window covering. There are many different kinds of window blinds which use a variety of control systems. A typical window blind is made up of several long horizontal or vertical slats of various types of hard material, including wood, plastic or metal which are held together by cords that run through the blind slats. Vertical blinds run along a track system which can tilt open and closed and move side-to-side. Window blinds can be manoeuvred with either a manual or remote control by rotating them from an open position, with slats spaced out, to a closed position where slats overlap and block out most of the light. There are also several types of window coverings, called shades, that use a single piece of soft material instead of slats. The term window blinds can also be used to describe window coverings more broadly. In this context window blinds include almost every type of window covering, whether it is a hard or soft material; i.e. shutters, rol ...

Dynamics (music)
In music, the dynamics of a piece are the variation in loudness between notes or phrases. Dynamics are indicated by specific musical notation, often in some detail. However, dynamics markings require interpretation by the performer depending on the musical context: a specific marking may correspond to a different volume between pieces or even sections of one piece. The execution of dynamics also extends beyond loudness to include changes in timbre and sometimes tempo rubato. Purpose and interpretation Dynamics are one of the expressive elements of music. Used effectively, dynamics help musicians sustain variety and interest in a musical performance, and communicate a particular emotional state or feeling. Dynamic markings are always relative. (''piano'' - "soft") never indicates a precise level of loudness; it merely indicates that music in a passage so marked should be considerably quieter than (''forte'' - "loud"). There are many factors affecting the interpretati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
American Guild Of Organists
The American Guild of Organists (AGO) is an international organization of academic, church, and concert organists in the US, headquartered in New York City with its administrative offices in the Interchurch Center. Founded as a professional educational association, it was chartered by the Board of Regents of the University of the State of New York in 1896, with the authority to grant certificates of associate or fellow to members who passed examinations. Membership is not limited to professional organists, but is open to anybody with an interest in organs and organ music. As of 2020, there are approximately 14,000 voting members in all categories of membership. The AGO's current president is Eileen Hunt, elected in 2022. The guild seeks to set and maintain high musical standards and to promote understanding and appreciation of all aspects of organ and choral music. Founders Among the 145 founding members of the guild were Benjamin Dwight Allen, John W. Bischoff, Dudley Buc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Boardwalk Hall Auditorium Organ
The Boardwalk Hall Auditorium Organ, also known as the Midmer-Losh and the Poseidon, is the pipe organ in the Main Auditorium of the landmark Boardwalk Hall (formerly known as Convention Hall) in Atlantic City, New Jersey. The musically versatile instrument was built by the Midmer-Losh Organ Company during 1929–1932. It is the largest organ in the world, as measured by the number of Organ pipe, pipes – officially 33,112, but the exact number is uncertain. After decades of accumulated damage from water, building renovations, neglect, and insufficient funding, beginning in the 1990s a $100 million restoration program is gradually returning the organ to full operability. The Main Auditorium was built as the world's largest unobstructed indoor space, a barrel vault measuring and enclosing of air. The Auditorium Organ runs on much higher wind pressures than most organs, to be loud enough to fill the enormous space acoustically without amplification. The organ was awarded four ent ...

Portative Organ
A portative organ (from the Latin verb , "to carry"), also known during Italian Trecento as the , is a small pipe organ that consists of one rank of flue pipes, sometimes arranged in two rows, to be played while strapped to the performer at a right angle. The performer manipulates the bellows with one hand and fingers the keys with the other. The portative organ lacks a reservoir to retain a supply of wind and so it produces sound only while the bellows are being operated. The instrument was commonly used in European secular music from the 12th to the 16th centuries. The Italian composer Francesco Landini is known to have played the instrument. There are performers on the instrument again as a result of the Early Music Revival. Some contemporary music has been written for it, for example by José María Sánchez-Verdú. Dolly Collins also used it in modern English folk music. Terminology The portative organ is also called a portatif organ, portativ organ, or simply portative, p ...

Cent (music)
The cent is a logarithmic unit of measure used for musical intervals. Twelve-tone equal temperament divides the octave into 12 semitones of 100 cents each. Typically, cents are used to express small intervals, to check intonation, or to compare the sizes of comparable intervals in different tuning systems. For humans, a single cent is too small to be perceived between successive notes. Cents, as described by Alexander John Ellis, follow a tradition of measuring intervals by logarithms that began with Juan Caramuel y Lobkowitz in the 17th century. Ellis chose to base his measures on the hundredth part of a semitone, \sqrt 200/math>, at Robert Holford Macdowell Bosanquet's suggestion. Making extensive measurements of musical instruments from around the world, Ellis used cents to report and compare the scales employed, and further described and utilized the system in his 1875 edition of Hermann von Helmholtz's ''On the Sensations of Tone''. It has become the standard me ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Equal Temperament
An equal temperament is a musical temperament or Musical tuning#Tuning systems, tuning system that approximates Just intonation, just intervals by dividing an octave (or other interval) into steps such that the ratio of the frequency, frequencies of any adjacent pair of notes is the same. This system yields Pitch (music), pitch steps perceived as equal in size, due to the logarithmic changes in pitch frequency. In classical music and Western music in general, the most common tuning system since the 18th century has been 12 equal temperament (also known as ''12 tone equal temperament'', ' or ', informally abbreviated as ''12 equal''), which divides the octave into 12 parts, all of which are equal on a logarithmic scale, with a ratio equal to the twelfth root of two, 12th root of 2, (\sqrt[12] ≈ 1.05946). That resulting smallest interval, the width of an octave, is called a semitone or half step. In Western world, Western countries the term ''equal temperamen ...
