+_Harpsichords and Clavichords_
+
+
+The harpsichord and the clavichord represent the two most important
+types of stringed keyboard instruments used from the 15th through the
+18th centuries. By the 19th century, the piano had become the most
+important domestic keyboard instrument.
+
+In this booklet are described a few of the restored Smithsonian
+harpsichords and clavichords that are occasionally on exhibit in the
+Hall of Musical Instruments or in use in the series of concerts
+sponsored by the Division of Musical Instruments. Models showing how the
+sound is produced on these instruments are also on exhibit.
+
+A complete list of the keyboard collection is found in _A Checklist of
+Keyboard Instruments at the Smithsonian Institution_ (Washington, 1967),
+which is available from the Division of Musical Instruments, Smithsonian
+Institution, Washington, D.C. 20560.
+
+
+
+
+_Harpsichords_
+
+
+The harpsichord and its smaller relatives, the virginal and the spinet,
+have strings that are _plucked_. The harpsichord is wing-shaped, most
+virginals and spinets are either rectangular or polygonal.
+
+When the harpsichord key is pressed, a wooden jack is raised so that a
+quill or leather plectrum inserted into the jack tongue plucks the
+string. When the key is released, the jack falls back into place, the
+pivoted tongue allowing the plectrum to pass the string without plucking
+it. A felt damper (inserted in a slit at the top of the jack) touches
+the string to stop the sound.
+
+Figure 1 shows the jack arrangement in an 18th century English spinet.
+The second jack from the left on the front row has been raised so that
+its quill is just about to pluck the string. Note that the quill has
+lifted the string above its rest position.
+
+Inherent in the design of a harpsichord is the limitation of dynamic
+nuance. The sound of a harpsichord is not greatly altered by increasing
+or lessening the impact of fingers on the keys. Rather, the dynamic
+level and quality of sound can be changed by varying the number of
+strings plucked (many harpsichords have three sets of strings: two sets
+tuned in unison [8′] and a third tuned an octave higher [4′]), by
+varying the location of the plucking point, and by muting the strings
+with felt or leather pads.
+
+The tone of a keyboard instrument is also affected by its general
+outline, the material and thickness of the soundboard, the length and
+material of the strings, and the type of case construction. The case
+must be strong enough to counteract the tension of the strings and yet
+light enough to allow the sound to resonate.
+
+[Illustration: 1. Harpsichord action. _Photo: Robert Lautman._]
+
+Among the Smithsonian’s extensive keyboard collection are fine examples
+of harpsichords that represent several of the major national trends in
+harpsichord building: the Flemish, Italian, English, and French.
+
+
+
+
+_Flemish Harpsichords_
+
+
+Antwerp was the harpsichord-making center of northern Europe during the
+16th and 17th centuries. The earliest examples of harpsichords had only
+one keyboard and one or two sets of 8′ strings. The progressive Flemish
+makers added a second keyboard and another set of strings, tuned an
+octave higher than the others, which allowed a wider range in pitch and
+more variety in sound. Later French and English harpsichords were
+largely derived from the Flemish style.
+
+
+Virginal, _1620; made by Andreas Ruckers, Antwerp One manual;
+Range C/E-c³ (apparent); 1×8′_
+
+[Illustration: 2. Ruckers virginal: Plan view.]
+
+[Illustration: 3. Ruckers virginal: Full view.]
+
+[Illustration: 4. Ruckers virginal: Detail of keyboard.
+_Photo: Robert Lautman_]
+
+[Illustration: 5. Ruckers virginal: View of soundboard and lid.
+_Photo: Robert Lautman_]
+
+Instruments built by the famous Ruckers family were and are still highly
+prized. Although simply painted on the exterior, the case of this
+virginal is decorated on the inside in characteristic Ruckers style.
+Block-printed papers cover the interior of the case; the inside of
+the lid bears a Latin motto and the soundboard is painted with flowers
+and arabesques. Figure 4 illustrates a detail of the block printing, and
+of the keys. The arcades on the end of the keys appear to be cut from
+several layers of leather which were then applied to the key fronts.
+
+This instrument is tuned a fourth higher than it might appear. When the
+C key is pressed, the note sounded is F, a fourth above.
+
+
+_Short-Octave Tuning_
+
+Since chromatic notes in the lowest octave of the keyboard were not
+often needed in the music of the 16th and 17th centuries, the practice
+of short-octave tuning was adopted.
+
+Although the lowest note on a short-octave instrument appears to be E,
+the range was actually extended down to C. (The notation C/E indicates
+this arrangement.)
+
+[Illustration: NORMAL TUNING]
+
+[Illustration: SHORT-OCTAVE TUNING]
+
+A typical short-octave instrument of the 16th and 17th centuries would
+be tuned in the following manner: E (1) is tuned down to C (I); F♯ (2)
+tuned to D (II); and G♯ (3) tuned to E (III).
+
+
+Harpsichord, _1745; made by Johann Daniel Dulcken, Antwerp Two manuals;
+Range FF-f³; 2×8v, 1×4′, lute_
+
+Typical of northern European instruments, the Dulcken harpsichord has a
+heavy case, two keyboards or manuals, and two 8′ choirs and one 4′
+choir. It also has a lute stop, whose jacks, very close to the nut,
+pluck one set of unison strings to produce a pungent, nasal tone.
+

+
+
+
+
+_Italian Harpsichords_
+
+
+Typical Italian harpsichords had two choirs of unison strings and two
+jacks for each key. They were of much lighter construction than those
+made in northern Europe—the sides of the case were only about an eighth
+of an inch thick. These fragile instruments were usually placed in
+heavier, often elaborately decorated, outer cases from which the
+harpsichord could be removed.
+
+
+Harpsichord, _1693; maker unknown, Italy One manual; Range GG-c³ (no
+GG♯); 2×8′_
+
+The typical construction of Italian harpsichords can be seen in this
+large Italian instrument. The original nameboard is missing; however, as
+was common practice, the maker marked the date on the tail of the lowest
+and highest keys.
+
+The Italian harpsichord serves as an ideal _basso continuo_ keyboard
+instrument because it blends well in instrumental combinations. Its
+clean, crisp sound also allows individual lines to emerge clearly from a
+polyphonic musical texture.
+
+[Illustration: 11. Italian harpsichord (1693): Full view of instrument
+in outer case.]
+
+[Illustration: 12. Italian harpsichord (1693): Plan view.]
+
+[Illustration: 13. Detail of keyboard. _Photo: Robert Lautman_.]
+
+
+Harpsichord, _1694; made by Nicolaus DeQuoco, Italy One-manual: Range
+C-c³ (no C♯); 2×8′, 1×4′_
+
+This instrument is one of the few examples of an Italian harpsichord
+with a third set of strings tuned an octave higher than the two unison
+choirs. It is possible that the third set was added to this instrument
+sometime after it was constructed with two unison registers.
+
+Figure 15 shows the instrument before restoration; Figures 14 and 16
+show the restored harpsichord removed from its heavy outer case and
+details of the handsome keyboard and moldings typical of Italian
+instruments.

+
+
+Virginal, _1617; made by Giovanni Battista Boni, Cortona One manual;
+Range C/E-f³; 1×8′_
+
+The smaller virginals and spinets were commonly found in homes of modest
+means, as well as in royal courts. This polygonal virginal has six split
+keys which represent a complicated tuning scheme.
+
+[Illustration: 21. Tuning scheme.]
+
+Keys 1-2: This is a system of short-octave tuning (see Ruckers Virginal)
+in which the two lowest accidentals are split into two sections. The
+back section is tuned to the apparent accidental, the front section to
+the short octave. Thus, on the Boni, the back section of the bottom
+split key is tuned F♯, the front section is tuned D; the back section of
+the second lowest split key is tuned A♭, the front section is tuned E.
+
+Keys 3-6: The top four keys are split to provide for enharmonic
+tuning—that is, both D♭ and E♭, G♯ and A♭. In the meantone system of
+tuning, which was the prevailing tuning of the time, scales distant from
+the key of C were often out of tune. To improve the intonation of these
+scales, some makers divided some of the accidental keys to provide
+alternate tunings.

+
+
+
+
+_English Harpsichords_
+
+
+In the 18th century, London became a center of harpsichord making. The
+two most important makers, Jacob Kirckman and Burkat Shudi, were Swiss
+immigrants who first apprenticed with Hermann Tabel, a Flemish
+harpsichord maker who had also emigrated to England. In America, where
+English culture was highly regarded, Thomas Jefferson owned a Kirckman
+harpsichord, Francis Hopkinson a Shudi and Broadwood.
+
+The heavy cases of the typical English instruments were veneered in
+walnut, mahogany, and later satinwood, and rested on trestle stands. The
+usual range was five octaves: FF-f³ for harpsichords; GG-g³ for
+spinets (and organs). In general, the sound produced on an English
+harpsichord is more thick and lush than the sound of instruments from
+other European centers.
+
+
+Spinet, _about 1710; made by Thomas Hitchcock, London One manual; Range
+GG-g³; 1×8′_
+
+The spinet, a member of the harpsichord family, was a popular domestic
+keyboard instrument in England and America during the 18th century and
+was mentioned in many American diaries and inventories of that time. The
+spinet often served as the keyboard instrument for the household that
+could not afford or did not have room for the harpsichord or organ.
+
+The Hitchcock family supplied many spinets for early 18th-century
+gentility. Note in Figure 24 the handsome brass hinges, one of many
+examples of the beautiful hardware used by English builders. This
+instrument is quilled with crow quill, the most common material used for
+plectra at that time. A detail of the jacks and stringing is shown in
+Figure 1.
+
+[Illustration: 22. Hitchcock spinet: Full view and nameboard.]
+
+[Illustration: 23. Hitchcock spinet: Plan view.]
+
+[Illustration: 24. Hitchcock spinet: Top view. _Photo: Robert Lautman_.]
+
+
+Harpsichord, _about 1743; made by Burkat Shudi, London Two manuals;
+Range FF-f³ (no FF♯); 2×8′, 1×4′, lute, buff_
+
+Most of the stops on early harpsichords were changed by hand. From left
+to right, the stop knobs shown in Figure 25 operate the following
+registers: _lute_, _octave_ (4′), _buff_ (muting the second unison by
+pressing soft leather pads against the strings), _first unison_ (8′),
+and _second unison_ (8′). The lute stop plays from the upper manual, the
+first unison from both manuals, and the remaining stops from the lower
+manual.
+
+Figures 25 and 26 show the instrument before restoration. The name
+batten on which the date of 1747 appears is not original to the
+instrument. The date of the instrument is based on the serial number 144
+stamped on the lower keyboard. From all records it appears Shudi would
+have built an instrument with that serial number in 1743.
+

+
+
+_French Harpsichords_
+
+
+Although Paris claimed many harpsichord builders, few French
+harpsichords remain today. Many were destroyed at the time of the
+Revolution and later when firewood was needed to heat Conservatoire
+classrooms.
+
+French builders, the most famous among them the Blanchet family and
+Pascal Taskin, spent much of their time reconstructing Ruckers
+harpsichords to satisfy the musical and decorative tastes of
+18th-century France. Included in this reconstruction or _ravalement_
+were the extension of compass (usually from C-c³ to FF-f³),
+enlargement of the case and soundboard, and often replacement of
+keyboards, jacks, and registers.
+
+Housed in elegantly painted cases supported by cabriole or fluted legs,
+typical French harpsichords had two manuals and were praised for their
+lightness of touch. Later 18th-century developments included a fourth
+register called _peau de buffle_ (plectra of soft chamois-type leather)
+and knee levers to operate the registers.
+
+
+Harpsichord, _1760; made by Benoist Stehlin, Paris Two manuals; Range
+FF-f³; 2×8′, 1×4v, buff, shove coupler_
+
+In recent years the Smithsonian was fortunate to acquire one of the few
+remaining French harpsichords. The builder’s name is known from the
+design on the soundboard rose which includes the initials “B” and “S”;
+also, the name “Benoist Stehlin” is inscribed on two of the jacks. The
+1760 date is painted on the left side of the soundboard. An inventory of
+Stehlin’s workshop and house made at the time of his death in 1774 lists
+a Ruckers harpsichord altered by Stehlin along with several other
+instruments in various stages of completion. Figures 28 and 30 show the
+instrument before its restoration.
+
+[Illustration: 28. Stehlin harpsichord: Full view.]
+
+This instrument was restored to playing condition in the conservation
+laboratory of the Division of Musical Instruments in 1968. Typical of
+most French instruments, it is equipped with a shove coupler, which
+enables the player to operate both manuals from the lower keyboard by
+shoving the upper keyboard away from him. In this pushed-back position,
+wooden uprights (dogs) attached to the upper surface of the far ends of
+the lower key levers couple the two manuals and cause the upper manual
+keys to descend when the lower manual keys are pressed.
+
+[Illustration: 29. Stehlin harpsichord: Detail of rose.]
+
+[Illustration: 30. Stehlin harpsichord: Plan view.]
+
+
+
+
+_Clavichords_
+
+
+Dynamic shadings are possible in the clavichord, as in the piano,
+through variation of finger pressure. In both, the strings are struck—by
+metal tangents in the clavichord and by leather or felt hammers in the
+piano.
+
+In the clavichord the strings extend over a soundboard bridge on the
+player’s right and are damped (stopped from vibrating) by strips of
+cloth on the left. The metal hammer (tangent) mounted in the end of the
+key strikes the string and continues to touch it as long as the player
+presses the key. The tangent, while touching the string, divides it into
+two segments—the segment on the right being free to vibrate, the segment
+on the left being damped by the cloth. When the key is released, the
+cloth damps the entire string.
+
+Figure 31 shows a player depressing a clavichord key (middle c). The
+tangent at the far end of the key lever has been raised so that it has
+struck the strings and has lifted them above rest position. The damping
+cloth on the left of this raised string can also be seen.
+
+Known as early as the 15th century, the clavichord produces tones,
+though limited in volume, that are very expressive and even capable of
+vibrato (_Bebung_). Because it lacks carrying power, the clavichord
+historically was a solo or practice instrument, for it could not be
+heard in combination with other instruments or with the voice.
+
+[Illustration: 31. Clavichord action. _Photo: Robert Lautman_.]
+
+
+Fretted Clavichord, _about 1700; maker unknown, Germany_
+
+Unfretted Clavichord, _18th century; maker unknown, Germany_
+
+The clavichord was usually housed in a rectangular case which rested
+upon a simple stand. The range of the earlier instruments was about four
+octaves. By the 18th century the range had been expanded to five
+octaves.
+
+The larger, later clavichords had separate strings for each key and were
+unfretted or _bundfrei_. Many smaller and earlier clavichords were
+fretted (_gebunden_), having some strings that would produce more than
+one pitch when struck at different points by adjacent keys.
+
+Figure 32 shows the fretted clavichord keyboard in more detail. Tangents
+on keys numbered 16 and 17 strike the same strings to produce the notes
+e♭ and e. Some other fretted notes shown in the picture include: keys 18
+and 19 (f and f♯), keys 20 and 21 (g and g♯]), keys 23 and 24 (b♭ and
+b), and keys 25 and 26 (middle c and c♯). Figure 31 is also a detail
+from this clavichord.
+
+The Smithsonian clavichord shown in Figures 35 and 36, in unrestored
+condition, is typical of the large unfretted instruments that became
+standard in Germany by the mid-18th century and for which Carl Philipp
+Emanuel Bach wrote many solo keyboard compositions.
+
+[Illustration: 32. Fretted clavichord: Detail of fretting.

+
+[Illustration: 35. Unfretted clavichord: Full view.]
+
+[Illustration: 36. Unfretted clavichord: Plan view.]
+
+By the beginning of the 18th century the desire was strong for a more
+expressive keyboard instrument to use in ensembles. Harpsichord builders
+added new stops, devised special leather plectra, and added Venetian
+swell effects and other innovations to alter the sound of the
+harpsichord. But no matter what they did, they could not produce enough
+dynamic gradation to satisfy musical taste. The clavichord was capable
+of dynamic nuance, but it lacked carrying power.
+
+Instrument builders, seeking to satisfy the demands created by the
+change in sensibility and musical taste, turned naturally to the
+domestic instruments they knew best—the harpsichord and clavichord—as
+the process of adaptation began. For this reason, as the pianoforte was
+developed and perfected, the general proportions and arrangement of the
+grand piano resembled those of the harpsichord. Similarly, the relation
+between the keyboard and strings, the scaling, and other features of the
+square piano resembled those of the clavichord.
+
+By the beginning of the 19th century the pianoforte, an instrument
+capable of subtle changes between soft and loud, had become the most
+important domestic and concert keyboard instrument. After 1800 few
+clavichords or harpsichords were built or used until they were revived
+by early music enthusiasts at the end of the 19th century.

+Section 2. Information about the Mission of Project Gutenberg-tm
+
+Project Gutenberg-tm is synonymous with the free distribution of
+electronic works in formats readable by the widest variety of computers
+including obsolete, old, middle-aged and new computers. It exists
+because of the efforts of hundreds of volunteers and donations from
+people in all walks of life.
+
+Volunteers and financial support to provide volunteers with the
+assistance they need are critical to reaching Project Gutenberg-tm's
+goals and ensuring that the Project Gutenberg-tm collection will
+remain freely available for generations to come. In 2001, the Project
+Gutenberg Literary Archive Foundation was created to provide a secure
+and permanent future for Project Gutenberg-tm and future generations.
+To learn more about the Project Gutenberg Literary Archive Foundation
+and how your efforts and donations can help, see Sections 3 and 4

+
+Section 4. Information about Donations to the Project Gutenberg
+Literary Archive Foundation
+
+Project Gutenberg-tm depends upon and cannot survive without wide
+spread public support and donations to carry out its mission of
+increasing the number of public domain and licensed works that can be
+freely distributed in machine readable form accessible by the widest
+array of equipment including outdated equipment. Many small donations
+($1 to $5,000) are particularly important to maintaining tax exempt
+status with the IRS.
+
+The Foundation is committed to complying with the laws regulating
+charities and charitable donations in all 50 states of the United
+States. Compliance requirements are not uniform and it takes a
+considerable effort, much paperwork and many fees to meet and keep up
+with these requirements. We do not solicit donations in locations
+where we have not received written confirmation of compliance. To
+SEND DONATIONS or determine the status of compliance for any
+particular state visit www.gutenberg.org/donate
+
+While we cannot and do not solicit contributions from states where we
+have not met the solicitation requirements, we know of no prohibition
+against accepting unsolicited donations from donors in such states who
+approach us with offers to donate.
+
+International donations are gratefully accepted, but we cannot make
+any statements concerning tax treatment of donations received from
+outside the United States. U.S. laws alone swamp our small staff.
+
+Please check the Project Gutenberg Web pages for current donation
+methods and addresses. Donations are accepted in a number of other
+ways including checks, online payments and credit card donations.
+To donate, please visit: www.gutenberg.org/donate

+
+Section 5. General Information About Project Gutenberg-tm electronic
+works.
+
+Professor Michael S. Hart was the originator of the Project Gutenberg-tm
+concept of a library of electronic works that could be freely shared
+with anyone. For forty years, he produced and distributed Project
+Gutenberg-tm eBooks with only a loose network of volunteer support.
+
+Project Gutenberg-tm eBooks are often created from several printed
+editions, all of which are confirmed as Public Domain in the U.S.
+unless a copyright notice is included. Thus, we do not necessarily
+keep eBooks in compliance with any particular paper edition.
+
+Most people start at our Web site which has the main PG search facility:
+
+ www.gutenberg.org
+
+This Web site includes information about Project Gutenberg-tm,
+including how to make donations to the Project Gutenberg Literary
+Archive Foundation, how to help produce our new eBooks, and how to
+subscribe to our email newsletter to hear about new eBooks.
