Fortepiano
In 1700, the Medici family inventory listed a new instrument called a gravicembalo col piano e forte. Bartolomeo Cristofori had built this device in Florence as a harpsichord maker by trade. The first surviving examples of his work date from the 1720s and now rest in museums like the Metropolitan Museum of Art. Cristofori did not simply attach his action to an existing frame; he designed thicker strings and a robust case to support them. His invention included pairs of strings struck by hammers that could vary volume based on touch. A journal article by Scipione Maffei published in 1711 brought public attention to the mechanism through a detailed diagram. This publication appeared again in German translation in 1725 within Johann Mattheson's Critica Musica. That text likely triggered the spread of the instrument into German-speaking regions. Early adoption remained slow because the fortepiano was expensive and difficult to construct compared to simpler instruments. It became an exclusive possession of royalty for decades. Queen Maria Barbara of Spain owned several such instruments during her lifetime. She taught the composer Domenico Scarlatti on one of these early models. After her death, the castrato Farinelli inherited one of her pianos. No commercial market existed for music written specifically for the instrument until the 1760s. Lodovico Giustini published Sonate da cimbalo di piano in 1732 as an isolated event honoring royal patrons rather than selling to the public.
Johann Andreas Stein worked in Augsburg starting around 1775 to create a distinct type of action known today as Viennese. His instruments featured backwards hammers with the striking end closer to the player than the hinge point. The force required to depress a key on a Stein fortepiano measured only about a fourth of that needed on a modern piano. Key descent also reached just half the distance of later designs. This mechanism lacked an escapement device found in Cristofori's original work but offered extreme sensitivity to touch. Mozart wrote a letter to his father in 1777 criticizing simpler actions lacking this feature yet acknowledging their popularity. Anton Walter built instruments in Vienna with slightly more powerful sound than Stein's while maintaining similar mechanics. Beethoven expressed a wish to purchase a Walter piano during his time in the city. Conrad Graf produced robust instruments in the early nineteenth century including one used by Chopin and Mendelssohn. Meanwhile Johannes Zumpe created inexpensive square pianos in London during the late 1760s using a simple action called old man's head. These square pianos displaced harpsichords through widespread imitation outside England. John Broadwood married Barbara Shudi in 1769 and took over her family firm. He collaborated with virtuoso Jan Ladislav Dussek to develop grand pianos reaching six octaves in range. A Broadwood piano shipped to Beethoven in Vienna became a treasured possession for the composer. English grands featured three strings per note instead of two and required deeper touch despite less sensitivity.
Starting from the late eighteenth century, fortepianos underwent extensive technological development toward what we now call the modern concert grand. By the late nineteenth century the older type ceased production entirely. Cristofori's original design lacked any metal frame or bracing found in later models. Later examples from the early nineteenth century began evolving toward heavier construction methods. The range expanded gradually from four octaves at invention to five octaves for Mozart and finally six and a half octaves for Beethoven's last compositions. Modern pianos attained seven octaves by the nineteenth century. Arnold Dolmetsch built three fortepianos in the late nineteenth century as an attempt to revive interest in period instruments. That effort failed to achieve widespread adoption decades before its time. The transition involved replacing leather-covered hammers with harder materials and adding iron frames for greater volume. Builders like Augustus Pleyel and Érard introduced innovations that increased string tension and durability. These changes allowed louder performances suitable for larger concert halls. The shift marked the end of the fortepiano era as public performance moved toward the new standard. Music schools eventually stopped teaching on historical instruments except for specialized study programs. The disappearance left many composers' works without their intended sonic context until much later.
Fortepianos vanished from public life after the mid-nineteenth century when modern grands took over. Interest returned only during the second half of the twentieth century alongside historically informed performance movements. Philip Belt spent two years working as an apprentice for Frank Hubbard while learning harpsichord construction techniques. He applied those skills to recreate early piano designs starting in the 1970s. Margaret F. Hood Rodney Regier Chris Maene and Paul McNulty joined him in building replicas based on surviving originals. Fortepiano kits became available allowing amateur builders to construct functional versions. Old instruments underwent restoration while new ones followed historical blueprints. Competitions emerged including the MAfestival Brugge and events organized by the Warsaw Chopin Institute. Performers such as Susan Alexander-Max Pieter-Jan Belder and Kristian Bezuidenhout achieved distinction playing these instruments. Malcolm Bilson taught courses at universities introducing students to period techniques. The revival enabled fresh insights into Haydn Mozart and Beethoven compositions written specifically for fortepianos. Schools began offering dedicated study tracks focusing on authentic execution methods. This movement transformed how audiences heard classical music from the eighteenth and early nineteenth centuries.
Leather-covered hammers struck thin strings resembling those found on harpsichords within a lightweight wooden case. No metal frame or bracing existed except in later examples approaching modern design standards. The action required minimal force yet produced expressive dynamics dependent on player sensitivity. Bass registers sounded slightly buzzing while high treble notes exhibited a tinkling quality. Mid-range tones remained rounded closer to modern piano characteristics. Sforzando accents stood out more clearly than on contemporary instruments due to rapid decay and timbral differences. Top notes dried quickly with short sustain compared to longer ringing sounds of modern grands. Marshall described the effect as tickling the ear through intentional color infusion across registers. Some players found certain sounds unpleasant despite their historical accuracy. Others believed clear sound favored special elements of style in Haydn and Mozart compositions. Gary Higginson noted metallic qualities could be subdued yet possessed profound beauty in expressive sonatas. Michael Cookson admitted discomfort with frequent unpleasantness despite loving authentic performances. Howland Auchincloss argued that initial reactions often changed after listening to good recordings. These tonal variations reflected deliberate choices made by builders like Stein Walter and Graf during their respective eras.
Bartolomeo Cristofori invented the instrument around 1700 under patronage from the Medici family in Florence. Gottfried Silbermann brought construction techniques to German-speaking nations starting circa 1730 in Freiberg. Frederick the Great bought many Silbermann instruments for his court. Johann Sebastian Bach criticized early models but approved later versions seen during a Berlin visit in 1747. Johann Andreas Stein developed backwards hammers used widely throughout Vienna until mid-nineteenth century. His daughter Nannette Streicher continued the business alongside husband Johann Andreas Streicher who befriended Beethoven. Anton Walter built powerful instruments admired by Mozart Haydn and desired by Beethoven himself. Conrad Graf created Beethoven's final piano before dying in 1851. French makers Érald Pleyel Boisselot gained prominence among composers like Chopin Liszt and Schumann. John Broadwood expanded range capabilities through collaboration with Jan Ladislav Dussek in London. These figures shaped both mechanical design and musical repertoire available during the classical era. Their names appear frequently in surviving letters scores and museum collections today. Modern specialists continue studying their methods to reconstruct authentic sounds accurately.
