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.
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, on electric and electronic keyboards, completing a circuit. Since the most commonly encountered keyboard instrument is the piano, the keyboard layout is often referred to as the piano keyboard.
A keyboard instrument is a musical instrument played using a keyboard, a row of levers that are pressed by the fingers. The most common of these are the piano, organ, and various electronic keyboards, including synthesizers and digital pianos. Other keyboard instruments include celestas, which are struck idiophones operated by a keyboard, and carillons, which are usually housed in bell towers or belfries of churches or municipal buildings.
The pipe organ is a musical instrument that produces sound by driving pressurised air through the organ pipes selected from a keyboard. Because each pipe produces a single pitch, the pipes are provided in sets called ranks, each of which has a common timbre, volume, and construction throughout the keyboard compass. Most organs have many ranks of pipes of differing pitch, timbre, and volume that the player can employ singly or in combination through the use of controls called stops.
In music, the organ is a keyboard instrument of one or more pipe divisions or other means for producing tones. The organs have usually two or three, up to five manuals, for playing with the hands, and pedalboard, with the feet. With the use of registers, several groups of pipes can be connected to one manual.
Bartolomeo Cristofori di Francesco was an Italian maker of musical instruments famous for inventing the piano.
A spinet is a smaller type of harpsichord or other keyboard instrument, such as a piano or organ.
The short octave was a method of assigning notes to keys in early keyboard instruments, for the purpose of giving the instrument an extended range in the bass range. The rationale behind this system was that the low notes F♯ and G♯ are seldom needed in early music. Deep bass notes typically form the root of the chord, and F♯ and G♯ chords were seldom used at this time. In contrast, low C and D, both roots of very common chords, are sorely missed if a harpsichord with lowest key E is tuned to match the keyboard layout. A closely related system, the broken octave, added more notes by using split keys: the front part and the back part of the (visible) key controlled separate levers and hence separate notes.
A key is a component of a musical instrument, the purpose and function of which depends on the instrument. However, the term is most often used in the context of keyboard instruments, in which case it refers to the exterior part of the instrument that the player physically interacts in the process of sound production.
The virginals is a keyboard instrument of the harpsichord family. It was popular in Europe during the late Renaissance and early Baroque periods.
An electric organ, also known as electronic organ, is an electronic keyboard instrument which was derived from the harmonium, pipe organ and theatre organ. Originally designed to imitate their sound, or orchestral sounds, it has since developed into several types of instruments:
A pedalboard is a keyboard played with the feet that is usually used to produce the low-pitched bass line of a piece of music. A pedalboard has long, narrow lever-style keys laid out in the same semitone scalar pattern as a manual keyboard, with longer keys for C, D, E, F, G, A, and B, and shorter, raised keys for C♯, D♯, F♯, G♯ and A♯. Training in pedal technique is part of standard organ pedagogy in church music and art music.
A clavicytherium is a harpsichord in which the soundboard and strings are mounted vertically facing the player. The primary purpose of making a harpsichord vertical is the same as in the later upright piano, namely to save floor space. In a clavicytherium, the jacks move horizontally without the assistance of gravity, so that clavicytherium actions are more complex than those of other harpsichords.
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.
A portative organ, also known during Italian Trecento as the organetto, 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, thus it will only produce sound while the bellows are being operated. The instrument was commonly used in European secular music from the 12th to the 16th centuries.
The regal is a small portable organ, furnished with beating reeds and having two bellows. The instrument enjoyed its greatest popularity during the Renaissance. The name was also sometimes given to the reed stops of a pipe organ, and more especially the vox humana stop.
An organ pipe, or a harpsichord string, designated as eight-foot pitch (8′) is sounded at standard, ordinary pitch. For example, the A above middle C in eight-foot pitch would be sounded at 440 Hz.
The oval spinet is a type of harpsichord invented in the late 17th century by Bartolomeo Cristofori, the Italian instrument maker who later achieved fame for inventing the piano. The oval spinet was unusual for its shape, the arrangement of its strings, and for its mechanism for changing registration.
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.
