A chiroplast is an instrument to guide the hands and fingers of pupils in playing on the piano, invented and patented by Johann Bernhard Logier in 1814. [1] [2] The instrument was an device that placed the wrist, thumb and fingers of a hand above five consecutive white keys of a keyboard, to overcome the difficulty of retaining their proper position by beginners. [1]
The device consisted of a wooden framework screwed into place over the whole length of the keyboard. [2] The user passed their wrists through two parallel wooden bars, which kept the wrists at the right level, and put their fingers into slots in two flat brass frames called "finger-guides" which could freely slide along a brass rod along the whole length of the keyboard. [2] Each finger-guide had five divisions, through which each finger was placed. [3] Each finger-guide was also attached to a stiff brass wire with a regulating screw, which kept the wrist in the proper position relative to the arm. [3] It was patented on 28 April 1814, patent no. 3806 "Apparatus for facilitating the acquirement of proper execution on the piano forte". The use of the chiroplast caused a significant amount of criticism and controversy, [1] at least part of which was due to the heavy opposition at the time to Logier's system for teaching multiple students at once, in which the chiroplast was a key part. [2]
A brass instrument is a musical instrument that produces sound by sympathetic vibration of air in a tubular resonator in sympathy with the vibration of the player's lips. Brass instruments are also called labrosones or labrophones, from Latin and Greek elements meaning 'lip' and 'sound'.
A musical keyboard is the set of adjacent depressible levers or keys on a musical instrument. Keyboards typically contain keys for playing the twelve notes of the Western musical scale, with a combination of larger, longer keys and smaller, shorter keys that repeats at the interval of an octave. Pressing a key on the keyboard makes the instrument produce sounds—either by mechanically striking a string or tine, plucking a string (harpsichord), causing air to flow through a pipe organ, striking a bell (carillon), or activating an electronic circuit. Since the most commonly encountered keyboard instrument is the piano, the keyboard layout is often referred to as the piano keyboard or simply piano keys.
The piano is a keyboard instrument that produces sound when its keys are depressed, through engagement of an action whose hammers strike strings. Modern pianos have a row of 88 black and white keys, tuned to a chromatic scale in equal temperament.
In musical instrument classification, string instruments or chordophones, are musical instruments that produce sound from vibrating strings when a performer plays or sounds the strings in some manner.
The Jankó keyboard is a musical keyboard layout for a piano designed by Paul von Jankó, a Hungarian pianist and engineer, in 1882. It was designed to overcome two limitations on the traditional piano keyboard: the large-scale geometry of the keys, and the fact that each scale has to be fingered differently. Instead of a single row, the Jankó keyboard has an array of keys consisting of two interleaved manuals with three touch-points for every key lever, making six rows of keys. Each vertical column of three keys is a semitone away from the neighboring ones, which are in the alternate rows. Thus within each row the interval from one note to the next is a whole step.
Friedrich Wilhelm Michael Kalkbrenner, also known as Frédéric Kalkbrenner, was a pianist, composer, piano teacher and piano manufacturer. German by birth, Kalkbrenner studied at the Conservatoire de Paris, starting at a young age and eventually settled in Paris, where he lived until his death in 1849. Kalkbrenner composed more than 200 piano works, as well as many piano concertos and operas.
Keyboard expression is the ability of a keyboard musical instrument to change tone or other qualities of the sound in response to velocity, pressure or other variations in how the performer depresses the keys of the musical keyboard. Expression types include:
The Flutina is an early precursor to the diatonic button accordion, having one or two rows of treble buttons, which are configured to have the tonic of the scale, on the "draw" of the bellows. There is usually no bass keyboard: the left hand operates an air valve. A rocker switch, called a "bascule d'harmonie" is in the front of the keyboard. When this switch is thumb activated, it would open up a pallet (a pad that covers a tone hole, at the other end of the key button, for a simple Tonic/Dominant drone: Tonic on the draw and Dominant on the press, e.g. Tonic notes C/g, and Dominant G/d, without any major or minor thirds.
In music, fingering, or on stringed instruments sometimes also called stopping, is the choice of which fingers and hand positions to use when playing certain musical instruments. Fingering typically changes throughout a piece; the challenge of choosing good fingering for a piece is to make the hand movements as comfortable as possible without changing hand position too often. A fingering can be the result of the working process of the composer, who puts it into the manuscript, an editor, who adds it into the printed score, or the performer, who puts his or her own fingering in the score or in performance.
Fingering...also stopping...(1) A system of symbols for the fingers of the hand used to associate specific notes with specific fingers....(2)Control of finger movements and position to achieve physiological efficiency, acoustical accuracy [frequency and amplitude] and musical articulation.
The piano action mechanism of a piano or other musical keyboard is the mechanical assembly which translates the depression of the keys into rapid motion of a hammer, which creates sound by striking the strings. Action can refer to that of a piano or other musical keyboards, including the electronic or digital stage piano and synthesizer, on which some models have "weighted keys", which simulate the touch and feel of an acoustic piano. The design of the key action mechanism determines the "weight" of the keys, i.e., the force required to sound a note; that is, the feeling of the heaviness of the touch of the keys. "A professional pianist is likely to care most about the piano's action, because that is what controls its responsiveness and relative lightness--or heaviness--of touch. Roughly speaking, a piano's action is light when its keys fall easily under the fingers, and heavy when a noticeable downward thrust is required. The action, in short, is what makes a piano playable or not to an individual musician."
An experimental musical instrument is a musical instrument that modifies or extends an existing instrument or class of instruments, or defines or creates a new class of instrument. Some are created through simple modifications, such as cracked cymbals or metal objects inserted between piano strings in a prepared piano. Some experimental instruments are created from household items like a homemade mute for brass instruments such as bathtub plugs. Other experimental instruments are created from electronic spare parts, or by mixing acoustic instruments with electric components.
Johann Bernhard Logier was a German composer, teacher, inventor, and publisher resident in Ireland for much of his life. He invented the chiroplast, a device to help students learn the piano, and developed one of the first systems for attempting to teach music in groups, which faced heavy opposition at the time.
Americus Backers, sometimes described as the father of the English grand pianoforte style, brought the hammer striking action for keyboard instruments from his master Gottfried Silbermann's workshop in Freiburg to England in the mid-18th century. Unlike the eleven other ex-apprentices of Silbermann who followed him to England and built square pianos with his action, Backers developed Silbermann's action into a reliable, powerful and responsive form that he built into a grand harpsichord case and added two tonal effects – una corda and damper lift – activated by pedals built into the dedicated trestle stand, again his original innovation. This new instrument altered the landscape of English music, causing composers and musicians to consign the plucked string harpsichord and its music to history. It is upon Americus's design that the modern grand pianoforte we know today is based.
The terpodion or uranion is a keyboard instrument which produces sound using the same friction principle as the glass harmonica.
John Eager (1782–1853?) was an English organist who taught the use of the chiroplast, a teaching instrument for learning the pianoforte, which was heavily criticized by conservative musicians. Between 1803 and 1833 he taught music in Yarmouth, England.
The minipiano is a very small upright piano patented by the Brasted brothers in 1934 under the name of their company Eavestaff Ltd. The primary factor that sets a minipiano apart is the fact that the action is positioned below the keyboard, allowing an economical use of space.
Music technology is the study or the use of any device, mechanism, machine or tool by a musician or composer to make or perform music; to compose, notate, playback or record songs or pieces; or to analyze or edit music.
Mechanical music technology is the use of any device, mechanism, machine or tool by a musician or composer to make or perform music; to compose, notate, play back or record songs or pieces; or to analyze or edit music. The earliest known applications of technology to music was prehistoric peoples' use of a tool to hand-drill holes in bones to make simple flutes. Ancient Egyptians developed stringed instruments, such as harps, lyres and lutes, which required making thin strings and some type of peg system for adjusting the pitch of the strings. Ancient Egyptians also used wind instruments such as double clarinets and percussion instruments such as cymbals. In Ancient Greece, instruments included the double-reed aulos and the lyre. Numerous instruments are referred to in the Bible, including the horn, pipe, lyre, harp, and bagpipe. During Biblical times, the cornet, flute, horn, organ, pipe, and trumpet were also used. During the Middle Ages, hand-written music notation was developed to write down the notes of religious Plainchant melodies; this notation enabled the Catholic church to disseminate the same chant melodies across its entire empire.
The keyed bugle is a wide conical bore brass instrument with tone holes operated by keys to alter the pitch and provide a full chromatic scale. It was developed from the bugle around 1800 and was popular in military bands in Europe and the United States in the early 19th century, and in Britain as late as the 1850s.
