This opening section presents the harpsichord as a plucked-string instrument that shaped Baroque music in Europe. History preserves precise examples, including the 1707 model built by Jean-Paul Rouaud after Nicolas Dumont.
The jack mechanism and internal structure clearly distinguish this early keyboard instrument from the modern piano. This article describes the construction choices that make the object both functional and decorative.
It discusses the instrument’s central place among Baroque composers, followed by its decline in the nineteenth century. By reading on, you will understand why this 1707 model is a technical and artistic achievement.
What is a harpsichord? A simple and complete definition
On instruments with several keyboards, delicate mechanisms pluck the strings to create the harpsichord’s distinctive timbre. This system relies on direct contact between a key and a jack that plucks a string.
A musical instrument with plucked strings, it comes in various forms. These include the full-size harpsichord, spinet and virginal, each suited to different uses.
Historically, this keyboard instrument occupied a central place in Baroque music. It often provided the basso continuo and accompanied the voice or other instruments.
Unlike percussion instruments, its volume cannot be varied through the force of the keystroke. Nuance instead comes from the player’s technique, registration and combination of keyboards.
Its complexity lies in the interaction between the mechanism and the sound. The combination of the keyboard, bridge and soundboard produces a tone rich in harmonics, characteristic of this instrument.
Origins and etymology of the term
The word comes from the Medieval Latin clavicymbalum, which already referred to a keyboard instrument with plucked strings.
During the seventeenth and eighteenthth centuries, harpsichords reached an artistic peak. They became the pre-eminent instruments of European aristocratic salons. This social status encouraged the rapid evolution of their construction and style.
The evolution of the name also reflects the history of music. For a long time, the term served as a generic designation for a family of plucked-string instruments.
- Etymology: clavicymbalum → modern name.
- History: peak in the seventeenth–eighteenthth centuries.
- Revival: rediscovery in the twentiethth century and reassessment of the repertoire.
This rediscovery restored the instrument to its place in the landscape of early music. To learn more about the origin of the term, see the page devoted to the clavicymbalum.
The structure of the soundbox
The shape and volume of the soundbox determine the instrument’s projection and timbre. A full-size model is generally 2 to 2.5 metres long and about one metre wide.
Construction materials
The case is often made of solid wood. This choice promotes better resonance and greater longevity.
The wood transmits the strings’ vibrations to the soundboard. The keyboard, built into a specific part of the case, provides a direct connection between the keys and the jacks.
With its elongated shape, the case can resemble a harp laid horizontally. The keyboard’s compass usually spans four and a half to five octaves, affecting string length and pitch measurement.
Role of the lid
The lid protects the strings and tuning mechanism. It also plays a major acoustic role.
When open, it reflects sound waves towards the listener and increases projection. Unlike the piano, early harpsichords have no metal frame, making the case lighter and altering the colour of the sound.
| Component | Material | Function |
|---|---|---|
| Case | Solid wood (maple, fir) | Main resonator, amplification |
| Soundboard | Thin spruce | Transmission of string vibrations |
| Lid | Varnished wood | Protection, sound reflection |
| Keyboard (section) | Inlaid wood | Mechanical connection to the jacks |
The crucial role of the plucked strings
The sound is born when the strings are plucked, with each vibration revealing delicate harmonics. The strings are the instrument’s sonic soul and give it a timbre very different from that of the piano.
Each note is produced when a jack plucks one or more strings. This mechanism conveys a crisp action, with no possibility of producing a crescendo through the key.
Tension is adjusted using the tuning pins. They keep the instrument in tune during a concert and facilitate adjustments before a performance.
The string choirs are often arranged in ranks. By selecting one or more choirs, the performer varies the colour and presence of the sound.
Unlike piano strings, those of this instrument are not wound. This absence of winding promotes clarity and precise attacks, qualities sought by harpsichordists.
How the soundboard works
The soundboard concentrates the strings’ energy and disperses it through the case. This component is a very thin piece of wood that transforms vibrations into audible sound.
Thickness and bracing
Its thickness generally ranges from 2.2 mm to 4.2 mm. The maker places reinforcing ribs beneath the soundboard to counteract the tension of the strings.
Role of the rose
The rose, often pierced or carved, helps air circulate within the case. It also has a decorative role and influences projection and tonal colour.
Transmission and decoration
Vibrations are transmitted through the bridge, a piece of hardwood glued to the soundboard. Flemish and French harpsichords frequently feature floral motifs on their surfaces, while Italian models are more restrained.
- Thin soundboard: amplification of the strings.
- Reinforcing ribs: structural stability.
- Bridge: essential point of contact.
Distinctive features of the keyboards
The arrangement of the keys and the connecting mechanism define the character of an early keyboard. This component determines the precision and speed of playing.
The upper manual
The upper manual often provides a brighter sound. On instruments with two keyboards, it allows rapid contrasts by coupling or separating the registers.
Compass: most span four and a half to five octaves, making it possible to perform virtuosic works with wide-ranging parts.
Natural keys and sharps
The natural keys, historically called naturals, sit alongside the chromatic keys, or sharps. Their raised profile facilitates playing and rhythmic precision.
Baroque pitch is often tuned to 415 Hz (and sometimes 392 Hz), affecting string tension and keyboard response.
Key decoration
Key finishes vary according to different building traditions. Bone is sometimes used for the naturals and ebony for the sharps.
“The decoration reveals the maker’s care and the importance given to the object in the workshop.”
- Two keyboards: more tonal colours through register coupling.
- Keys: an aesthetic and functional choice.
- Soundboard: influences transmission and clarity.

The internal jack mechanism
The jack acts like a small mechanical arm that transforms pressure on a key into the plucking of a string. This component is the centrepiece of the harpsichord’s mechanism and controls the attack of every note.
Each jack carries a plectrum, often made of quill or plastic. The plectrum lifts the string and then releases it to produce the sound. The action is short, crisp and repeatable across the keyboard’s entire compass.
A damper attached to the jack rests on the strings as soon as the key is released. It stops the vibration and controls the note’s duration. The precision of this assembly therefore directly affects clarity and articulation.
The case houses the jacks, which are guided by registers used to select the various string choirs. The consistency of the mechanism ensures a fast, even response across the entire keyboard.
- Precision: essential for an even attack.
- Plectrum: its material influences the timbre.
- Damper: controls the duration of the note.
The different stops and their sound
The foot designations of the stops explain why the same chord sounds different depending on the registration.
On a harpsichord, stops are designated 16′, 8′, 4′ or 2′. The 8′ is the most common and provides the principal colour.
The 4′ adds brilliance and harmonics. The jacks associated with each stop pluck separate strings to create these nuances.
On instruments with two keyboards, the musician can couple stops. This technique creates striking contrasts in timbre and makes it easier to move from a gentle piece to a powerful full registration.
The full registration combines several jack registers to enrich the harmonic texture. Selection is made using movable registers that engage or disengage the jacks corresponding to the chosen strings.
| Measurement (feet) | Sound effect | Use |
|---|---|---|
| 16′ | Lower sound, reinforced bass | Foundation for pedal parts and bass |
| 8′ | Principal colour, balance | Standard stop for most pieces |
| 4′ | Brilliance, upper harmonics | Added sparkle and articulation |
| 2′ | Very high sound, increased presence | Occasional effects or ornaments |

Historical variants of the family
Among the derived forms, the spinet and virginal offer compact versions of the same plucked-string mechanism.
The spinet
The spinet is distinguished by a narrower case and strings arranged at an angle.
The maker adapted the soundboard to maximise resonance despite the small volume. The jack mechanism and keyboard remain unchanged.
The virginal
The virginal is often rectangular and shorter than the full-size instrument.
Its keyboard compass could be reduced without changing the playing principle. Craftspeople adjusted the legs and the shape of the case to optimise projection.
These variants demonstrate the ingenuity of makers who adapted the instrument to the needs of salons and chapels.
| Characteristic | Spinet | Virginal |
|---|---|---|
| Shape | Angled, compact case | Rectangular, short |
| Keyboard | Possibly reduced compass | Shorter keyboard, but identical function |
| Soundboard and case | Soundboard adapted for resonance | Case modified for projection |
| Use | Confined spaces, teaching | Salons, vocal accompaniment |

Evolution and place in music history
From the sixteenth to the eighteenth century, the harpsichord established itself as the leading voice of secular music in Europe’s courts and salons.
Construction evolved continuously: craftspeople and makers adapted string length, the number of stops and the keyboard mechanism to meet composers’ tastes.
The instrument entered a period of decline in the nineteenth century. The piano, capable of a wider dynamic range, gradually replaced it in concert programmes.
Composers then turned to the piano, marking an important transition in music history.
The twentieth century brought a revival. The rediscovery of the early repertoire restored harpsichords to the centre of scholarship and historically informed performance.
- Sixteenth–eighteenth centuries: dominance in secular music.
- Nineteenth century: decline in the face of the piano.
- Twentieth century: revival and musicological interest.
| Period | Role | Impact |
|---|---|---|
| Sixteenth–eighteenth centuries | Principal instrument of the courts | Development of repertoire and building techniques |
| Nineteenth century | Replaced by the piano | Reorientation of the repertoire towards new dynamics |
| Twentieth century–today | Historical revival | Return of performances on period instruments |

Famous makers and building traditions
Ruckers, Blanchet and Taskin embody the lineage of masters who established harpsichord standards in the seventeenth and eighteenth centuries.
Each maker developed individual solutions for bracing the soundboard. These secrets ensured tuning stability and tonal quality.
National schools differed markedly. In France, the case and decoration followed a precise aesthetic, whereas resonance took precedence over ornament in Flanders.
In the eighteenth century, this expertise reached a level of technical perfection that continues to influence modern building.
“The choice of ribs and the way the soundboard is braced often form the signature of a workshop.”
- Ruckers: Flemish influence on harmonic richness.
- Blanchet: French refinement of proportions.
- Taskin: mechanical innovations and meticulous finishing.
| Maker | School | Signature |
|---|---|---|
| Ruckers | Flanders | Broader soundboards, warm sound |
| Blanchet | France | Balance between clarity and decoration |
| Taskin | France | Meticulous finishes, improved mechanism |
The legacy of these craftspeople inspires today’s builders and restorers. Historical models serve as references for reproducing the instrument’s authentic voice.
The harpsichord compared with the piano
In the eighteenth century, the fortepiano transformed keyboard playing by offering nuances that the plucked-string instrument could not achieve.
The piano uses hammers that strike the strings. This mechanism allows variations in intensity according to the touch. It quickly won over composers and court audiences.
Haydn and Mozart composed for the harpsichord before adopting the piano. Their transition illustrates the evolution of musical tastes over the course of the century.
The invention of double escapement on pianos reinforced that instrument’s expressive superiority. This technique enabled smoother playing and rapid repetitions on the keyboard.
Harpsichords nevertheless retain a unique sound, rich in harmonics thanks to their string choirs and distinctive cases. Their timbre remains prized in historically informed performance.
In summary: the piano prevailed because of its dynamic capabilities, but the earlier instrument retained an essential place in the sound palette of early music.
Repertoire and emblematic works
Keyboard literature evolved over several centuries, offering works imbued with both virtuosity and intimacy.
The harpsichord repertoire is immense. It includes works that explore technique, registration and string colour.
For example, the ornamented music of François Couperin perfectly illustrates the relationship between the musician’s gesture and the instrument’s voice.
Over the centuries, court and salon composers enriched the collection of works. This evolution sometimes led to piano adaptations that alter the original spirit of the pieces.
“Original works retain a soul that calls for the timbre and mechanism of the early keyboard.”
Today, these works continue to be performed and studied. They attest to the vitality of the repertoire and its central role in music history.
| Period | Type of works | Use |
|---|---|---|
| Sixteenth–eighteenth centuries | Suites, ornamented pieces, preludes | Court, salon, basso continuo |
| Nineteenth century | Piano transcriptions | Concerts and conservatoires |
| Twentieth century–today | Historical performances, recordings | Research, specialist concerts |
