Mechanism
Harpsichords vary in size and shape, but they all have the same basic functional arrangement. The player depresses a key pivoted in the middle of its length, which causes the far end of the key to rise. This lifts a jack, a long strip of wood, to which is attached a small plectrum (a wedge-shaped piece of quill or, nowadays plastic), which plucks the string. When the key is released by the player, the far end returns to its rest position and the jack falls back. The plectrum, mounted on a tongue that can swivel backwards away from the string, passes the string without plucking it again. As the key reaches its rest position, the string's vibrations are halted by the damper, a piece of felt attached to the top of the jack.
These basic principles are explained in more detail below.
Figure 1. Schematic view of a 2 8' single manual harpsichord
The keylever is a simple pivot, which rocks on a balance pin passing through a hole drilled through it.
The jack is a thin, rectangular piece of wood which sits upright on the end of the keylever, held in place by the registers (the upper movable, the lower fixed) which are two long strips of wood running in the gap from spine to cheek with rectangular mortises through which the jacks can move up and down.
Figure 2. Upper part of a jack
In the jack, a plectrum juts out almost horizontally (normally the plectrum is angled upwards a tiny amount) and passes just under the string. Historically, plectra were normally made of crow quill or leather; most modern harpsichords based on historic instruments have plastic (delrin or celcon) quills.
When the front of the key is pressed, the back of the key rises, the jack is lifted, and the plectrum plucks the string.
Figure 3. When the key is pressed, the jack is raised, and the plectrum touches the string and begins to bend. Then the plectrum plucks the string and causes it to sound. The jack hits the jack rail. When the player's hand is released from the key, the jack falls back down under its own weight, and the plectrum pivots backwards to allow it to pass the string.
When the key is lowered, the jack falls back down under its own weight, and the plectrum pivots backwards to allow it to pass the string. This is made possible by having the plectrum held in a tongue which is attached with a pivot and a spring to the body of the jack.
At the top of the jack, the felt damper keeps the string from vibrating when the key is not depressed.
The vertical rise of the jacks is stopped by the jackrail, which is covered with soft felt to muffle the impact of the jack.
Strings, tuning, and soundboard
Each string is wound around a tuning pin, normally at the end of the string which is closer to the player. When rotated with a wrench or tuning hammer, the tuning pin adjusts the tension so that the string will sound the correct pitch. Tuning pins are held tightly in holes drilled in the pinblock or wrestplank, an oblong hardwood plank.
Proceeding from the tuning pin, a string next passes over the nut, a sharp edge that is made of hardwood and is normally attached to the wrestplank. The section of the string beyond the nut forms its vibrating length, which is plucked and creates sound.
At the other end of its vibrating length, the string passes over the bridge, another sharp edge made of hardwood. As with the nut, the horizontal position of the string along the bridge is determined by a vertical pin inserted into the bridge, against which the string rests.
The bridge itself rests on a soundboard, a thin panel of wood usually made of spruce or (in Italian harpsichords) cedar. The soundboard efficiently transduces the vibrations of the strings into vibrations in the air; without a soundboard, the strings would produce only a very feeble sound.
A string is attached at its far end by a loop to a hitchpin which secures it to the case.
Multiple choirs of strings
Many harpsichords have exactly one string per note. There are several reasons why it is sometimes an advantage to have more. When there are two choirs of strings at the same length, it is possible to arrange for them to give different tonal qualities, and thus to increase the variety of sound produced by the instrument. This is done by having one set of strings plucked closer to the nut, which emphasizes the higher harmonics, and produces a "nasal" sound quality. When two strings tuned to be the same pitch, or to an octave apart, are plucked simultaneously by a single keystroke, the note is louder and richer than one produced by a single string. The qualitative distinction is particularly noticeable when the strings are tuned an octave apart.
When describing a harpsichord it is customary to specify its choirs of strings, often called its disposition. Strings at eight foot pitch sound at the normal expected pitch, strings at four foot pitch sound an octave higher, and sometimes harpsichords have the rare 16-foot pitch (one octave lower than eight-foot) or two-foot pitch (two octaves higher).
When there are multiple choirs of strings, the player is often able to control which choirs sound. This is usually done by having a set of jacks for each choir, and a mechanism for "turning off" each set, often by moving the upper register (through which the jacks slide) sideways a short distance, so that their plectra miss the strings. In simpler instruments this is done by manually moving the registers, but as the harpsichord evolved, builders invented levers, knee levers and pedal mechanisms to make it easier to change registration.
More flexibility in selecting which strings play is available in harpsichords having more than one keyboard or manual, since each manual can control the plucking of a different set of strings. In addition, such harpsichords often have a mechanism to couple manuals together, so that two can be used while actually playing on only one. The most flexible system is the French shove coupler, in which the lower manual can slide forward and backward, so that in the backward position "dogs" attached to the upper surface of the lower manual engage the lower surface of the upper manual's keys. Depending on choice of keyboard and coupler position, the player can select any of the sets of jacks labeled in figure 4 as A, or B and C, or all three.
Figure 4. French shove coupler. To the left: uncoupled keyboards. The depressed upper key lifts the jack A upwards. The depressed lower key lifts jacks B and C. To the right: The upper keyboard is coupled to the lower one by pulling the latter. The depressed upper key lifts the jack A upwards. The depressed lower key lifts jacks A, B and C.
The English dogleg jack system is less flexible, in that the manuals are immobile. The dogleg shape of the set of jacks labeled A in Figure 5 permits A to be played by either keyboard, but the lower manual necessarily plays all three sets, and the player cannot select just B and C as in the French shove coupler.
Figure 5. Dogleg jack, English coupler system. When depressed, the upper key lifts the "dogleg" jack (jack A) upwards. The lower key lifts all three jacks A, B, and C.
The use of multiple manuals in a harpsichord was not originally provided for the flexibility in choosing which strings would sound, but rather for transposition; for discussion see History of the harpsichord.
Jan Vermeer's famous painting A Lady Standing at a Virginal shows the characteristic practice of his time, with the instrument mounted on a table and the player standing.
The case
The case holds in position all of the important structural members: pinblock, soundboard, hitchpins, keyboard, and the jack action. It usually includes a solid bottom, and also internal bracing to maintain its form without warping under the tension of the strings. Cases vary greatly in weight and sturdiness: Italian harpsichords are often of light construction; heavier construction is found in the later Flemish instruments and those derived from them (see History of the harpsichord).
The case also gives the harpsichord its external appearance and protects the instrument. A large harpsichord is, in a sense, a piece of furniture, as it stands alone on legs and may be styled in the manner of other furniture of its place and period. Early Italian instruments, on the other hand, were so light in construction that they were treated rather like a violin: kept for storage in a protective outer case, and played after taking it out of its case and placing it on a table. Such tables were often quite high - until the late 18th century people usually played standing up. Eventually, harpsichords came to be built with just a single case, though an intermediate stage also existed: the "false inneruter", which for purely aesthetic reasons was built to look as if the outer case contained an inner one, in the old style.. Even after harpsichords became self-encased objects, they often were supported by separate stands, and some modern harpsichords have separate legs for improved portability.
Many harpsichords have a lid that can be raised, a cover for the keyboard, and a stand for music.
Harpsichords have been decorated in a great many different ways: with plain buff paint (e.g. some Flemish instruments), with paper printed with patterns, with leather or velvet coverings, with chinoiserie, or occasionally with highly elaborate painted artwork.
Variants
The terms used to denote the various members of the harpsichord family are now standardized. This was not so in the harpsichord's heyday.
Harpsichord
In modern usage, "harpsichord" can mean any member of the family of instruments. More often, though, it specifically denotes a grand-piano-shaped instrument with a roughly triangular case accommodating long bass strings at the left and short treble strings at the right. The characteristic profile of such a harpsichord is more elongated than a modern piano, with a sharper curve to the bentside.
Virginals
Main article: Virginals
The virginals is a smaller and simpler rectangular form of the harpsichord having only one string per note; the strings run parallel to the keyboard, which is on the long side of the case.
Spinet
Main article: Spinet
A spinet is a harpsichord with the strings set at an angle (usually about 30 degrees) to the keyboard. The strings are too close together for the jacks to fit between them. Instead, the strings are arranged in pairs, and the jacks are in the larger gaps between the pairs. The two jacks in each gap face in opposite directions, and each plucks a string adjacent to a gap. This produces a dry tone.
It is a rather a quiet instrument
Clavicytherium
A clavicytherium is a harpsichord with the soundboard and strings mounted vertically facing the player, the same space-saving principle as an upright piano. In a clavicytherium, the jacks move horizontally without the assistance of gravity, so that clavicytherium actions are more complex than those of other harpsichords.
Some of the earliest harpsichords for which we have evidence are clavicytheria. One surviving example from the late 15th century is kept at the Royal College of Music in London. For most of the history of the harpsichord, however, the clavicytherium was far less common than the horizontal instrument, probably because of its greater complexity and lesser reliability. In the 18th century fine clavicytheria were made by Albertus Delin, a Flemish builder..
Ottavino
Ottavini are small spinets or virginals at four foot pitch. It is thought that harpsichords at octave pitch were more common in the late Medival times and the early Renaissance, but lessened in popularity later on. However, ottavini remained very popular as domestic instruments in Italy. In England, Samuel Pepys makes many mentions of his "tryangle" in his diary, which references the usual shape of these instruments. In the Low Countries, ottavini were commonly paired with an 8' virginals, encased in a small cubb under the soundboard. The ottavino could be removed and placed on top of the larger virginal, making an effect like unto a double manual instrument. These are sometimes called 'mother-and-child'[citation needed] or 'double' virginals.
Other
The archicembalo, built in the 16th century, had an unusual keyboard layout, designed to accommodate variant tuning systems demanded by compositional practice and theoretical experimentation. More common were instruments with split sharps, also designed to accommodate the tuning systems of the time.
The folding harpsichord was an instrument that could be folded up for travel.
Harpsichord by Alastair McAllister, Melbourne, 1999, and a rare pedal harpsichord, by Hubbard & Broekman, Boston, 1990
Occasionally, harpsichords were built with a pedal keyboard. While these were mostly intended as practice instruments for organists, there are some pieces composed specifically for the pedal harpsichord.[citation needed]
Compass and pitch range
On the whole, earlier harpsichords have smaller ranges and later ones larger, though there are many exceptions. The largest harpsichords have a range of just over five octaves and the smallest have under four. Usually, the shortest keyboards were given extended range in the bass with a "short octave".
Tuning pitch is often taken to be a=415 Hz, roughly a semitone lower than the modern standard concert pitch of a=440 Hz. An accepted exception is for French baroque repertoire which is often performed with a=392 Hz, approximately a semitone lower again. Tuning an instrument nowadays usually starts with setting an A; historically it would commence from a C or an F.
History
Ruckers-Taskin (1646/1780) harpsichord, (Paris, Muse de la Musique)
Main article: History of the harpsichord
The harpsichord was most probably invented in the late Middle Ages. By the 1500s, harpsichord makers in Italy were making lightweight instruments with low string tension. A different approach was taken in Flanders starting in the late 1500s, notably by the Ruckers family. Their harpsichords used a heavier construction and produced a more powerful and distinctive tone. They included the first harpsichords with two keyboards, used for transposition.
The Flemish instruments served as the model for 18th century harpsichord construction in other nations. In France, the double keyboards were adapted to control different choirs of strings, making a musically more flexible instrument. Instruments from the peak of the French tradition, by makers such as the Blanchet family and Pascal Taskin, are among the most widely admired of all harpsichords, and are frequently used as models for the construction of modern instruments. In England, the Kirkman and Shudi firms produced sophisticated harpsichords of great power and sonority. German builders extended the sound repertoire of the instrument by adding sixteen foot and two foot choirs; these instruments have recently served as models for modern builders.
In the late 18th century the harpsichord was supplanted by the piano and almost disappeared from view for most of the 19th century: an exception was its continued use in opera for accompanying recitative, but the piano sometimes displaced it even there. 20th century efforts to revive the harpsichord began with instruments that used piano technology, with heavy strings and metal frames. Starting in the middle of the 20th century, ideas about harpsichord making underwent a major change, when builders such as Frank Hubbard, William Dowd, and Martin Skowroneck sought to re-establish the building traditions of the Baroque period. Harpsichords of this type of historically informed building practice dominate the current scene.
Music for the harpsichord
From the 16th century to the baroque
The first music written specifically for solo harpsichord was published around the early 16th century. Composers who wrote solo harpsichord music were numerous during the whole baroque era in European countries including Italy, Germany, England and France. Solo harpsichord compositions included dance suites, fantasias, and fugues. Besides solo works, the harpsichord was widely used for accompaniment in the basso continuo style (a function it maintained in operatic recitative even into the 19th century). Well into the 18th century, the harpsichord was considered to have some advantages over the piano.
After the baroque
Through the 19th century, the harpsichord was almost completely supplanted by the piano. In the 20th century, composers returned to the instrument, as they sought out variation in the sounds available to them. Under the influence of Arnold Dolmetsch, Violet Gordon-Woodhouse (18721951) and in France, Wanda Landowska (1879-1959), were at the forefront of the instrument's renaissance.
Concertos for the instrument were written by Francis Poulenc (the Concert champtre, 192728), Manuel de Falla, Bertold Hummel, Henryk Mikoaj Grecki, Michael Nyman, Philip Glass, and Roberto Carnevale. Bohuslav Martin wrote both a concerto and a sonata for the instrument, and Elliott Carter's Double Concerto is scored for harpsichord, piano and two chamber orchestras.
In chamber music, Gyrgy Ligeti wrote a small number of solo works for the instrument (including "Continuum"), and Henri Dutilleux's "Les Citations" (1991) is scored for harpsichord, oboe, double bass and percussions. Josef Tal wrote "Concerto for harpsichord & electronic music" (1964) and "Chamber Music" (1982) for s-recorder, marimba & harpsichord. Both Dmitri Shostakovich (Hamlet, 1964) and Alfred Schnittke (Symphony No.8, 1998) wrote works that use the harpsichord as part of the orchestral texture.
Harpsichordist Hendrik Bouman has composed pieces in the 17th and 18th century style, including works for solo harpsichord, harpsichord concerti, and other works that call for harpsichord continuo. Other contemporary composers writing new harpsichord music in period styles include Grant Colburn, Miguel Robaina, Fernando de Luca and Gianluca Bersanetti.
During the second half of the 20th century, the sound of the harpsichord (or perhaps rather more often, its electronically-created equivalent) became very familiar in popular culture, appearing frequently in popular music, television, films, computer games, and so on.
