A harpsichord is a musical instrument played by means of a keyboard. This activates a row of levers that turn a trigger mechanism that plucks one or more strings with a small plectrum made from quill or plastic. The strings are under tension on a 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, and even a pedal board. Harpsichords may also have stop buttons 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 piano is a keyboard instrument that produces sound when pressed on the keys. Most modern pianos have a row of 88 black and white keys: 52 white keys for the notes of the C major scale and 36 shorter black keys raised above the white keys and set further back, for sharps and flats. This means that the piano can play 88 different pitches, spanning a range of a bit over seven octaves. The black keys are for the "accidentals", which are needed to play in all twelve keys.
A digital piano is a type of electronic keyboard instrument designed to serve primarily as an alternative to the traditional acoustic piano, both in how it feels to play and in the sound it produces. Digital pianos use either synthesized emulation or recorded samples of an acoustic piano, which are played through one of more internal loudspeakers. They also incorporate weighted keys, which recreate the feel of an acoustic piano. Some digital pianos are designed to also look like an upright or grand piano. Others may be very simple, without a stand.
An electric piano is a musical instrument which produces sounds when a performer presses the keys of a piano-style musical keyboard. Pressing keys causes mechanical hammers to strike metal strings, metal reeds or wire tines, leading to vibrations which are converted into electrical signals by pickups which are then connected to an instrument amplifier and loudspeaker to make a sound loud enough for the performer and audience to hear. Unlike a synthesizer, the electric piano is not an electronic instrument. Instead, it is an electro-mechanical instrument. Some early electric pianos used lengths of wire to produce the tone, like a traditional piano. Smaller electric pianos used short slivers of steel to produce the tone. The earliest electric pianos were invented in the late 1920s; the 1929 Neo-Bechstein electric grand piano was among the first. Probably the earliest stringless model was Lloyd Loar's Vivi-Tone Clavier. A few other noteworthy producers of electric pianos include Baldwin Piano and Organ Company and the Wurlitzer Company.
An electronic keyboard, portable keyboard, or digital keyboard is an electronic musical instrument based on keyboard instruments. Electronic keyboards include synthesizers, digital pianos, stage pianos, electronic organs and digital audio workstations. In technical terms, an electronic keyboard is a synthesizer with a low-wattage power amplifier and small loudspeakers.
Piano construction is by now a rather conservative area; most of the technological advances were made by about 1900, and indeed it is possible that some contemporary piano buyers might actually be suspicious of pianos that are made differently from the older kind. Yet piano manufacturers, especially the smaller ones, are still experimenting with ways to build better pianos.
A fortepiano[ˌfɔrteˈpjaːno], sometimes referred to as a pianoforte, is an early piano. In principle, the word "fortepiano" can designate any piano dating from the invention of the instrument by Bartolomeo Cristofori in 1698 up to the early 19th century. Most typically, however, it is used to refer to the mid-18th to early-19th century instruments, for which composers of the Classical era, especially Haydn, Mozart, and the younger Beethoven and Hummel, wrote their piano music.
Kawai Musical Instruments Manufacturing Co., Ltd. is a musical instrument manufacturing company headquartered in Hamamatsu, Shizuoka, Japan. It is best known for its grand pianos, upright pianos, digital pianos, electronic keyboards and electronic synthesizers. The company was founded in August 1927.
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:
A MIDI keyboard or controller keyboard is typically a piano-style electronic musical keyboard, often with other buttons, wheels and sliders, used for sending MIDI signals or commands over a USB or MIDI 5-pin cable to other musical devices or computers. MIDI keyboards lacking an onboard sound module cannot produce sounds themselves, however some models of MIDI keyboards contain both a MIDI controller and sound module, allowing them to operate independently. When used as a MIDI controller, MIDI information on keys or buttons the performer has pressed is sent to a receiving device capable of creating sound through modeling synthesis, sample playback, or an analog hardware instrument. The receiving device could be:
The Wurlitzer electronic piano is an electric piano manufactured and marketed by Wurlitzer from 1954 to 1983. Sound is generated by striking a metal reed with a hammer, which induces an electric current in a pickup. It is conceptually similar to the Rhodes piano, though the sound is different.
Helpinstill is a US-based company that produces a unique electromagnetic pickup system for amplifying grand and upright pianos on stage. During the late 1970s the company also marketed a range of portable pianos ready-fitted with the pickups. These instruments were built by Kimball to Helpinstill's specifications. The company's founder and namesake, Charles Helpinstill, performs in Houston with his band, Ezra Charles and The Texas Blues Band.
Gottfried Silbermann was a German builder of keyboard instruments. He built harpsichords, clavichords, organs, and fortepianos; his modern reputation rests mainly on the latter two.
Johannes Zumpe was a leading maker of early English square pianos, a form of rectangular piano with a compass of about five octaves. The pianos sounded like mellow harpsichords, and had a damper stop in the left cheek of the case. Zumpe is known as the creator of English square pianos.
The scale length of a string instrument is the maximum vibrating length of the strings that produce sound, and determines the range of tones that string can produce at a given tension. It is also called string length. On instruments in which strings are not "stopped" or divided in length, it is the actual length of string between the nut and the bridge.
Guillaume-Lebrecht Petzold was a piano maker in Paris in the early 19th century.
Piano pedals are foot-operated levers at the base of a piano that change the instrument's sound in various ways. Modern pianos usually have three pedals, from left to right, the soft pedal, the sostenuto pedal, and the sustaining pedal. Some pianos omit the sostenuto pedal, or have a middle pedal with a different purpose such as a muting function also known as silent piano.
Finchcocks is an early Georgian manor house in Goudhurst, Kent. For 45 years it housed a large, visitor-friendly museum of historical keyboard instruments, displaying a collection of harpsichords, clavichords, fortepianos, square pianos, organs and other musical instruments. The museum was run by the owners of the house, Richard and Katrina Burnett. It is now owned by Neil and Harriet Nichols who use it as a family home and a venue for residential piano courses.
Robert Wornum (1780–1852) was a piano maker working in London during the first half of the 19th century. He is best known for introducing small cottage and oblique uprights and an action considered to be the predecessor of the modern upright action which was used in Europe through the early 20th century. His piano manufacturing business eventually became Robert Wornum & Sons and continued half a century after his death.
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.
