Fortepiano

From Wikipedia, the free encyclopedia

Fortepiano designates the early version of the piano, from its invention by the Italian instrument maker Bartolomeo Cristofori around 1700 up to the early 19th century. The term pianoforte is also sometimes used, but fortepiano is the preferred nomenclature.

The dynamic expression fortepiano is also used in a musical score, usually with the abbreviation fp, to designate a section of music in which the music should be played loudly (forte), then immediately softly (piano).

[edit] Construction

The fortepiano has leather-covered hammers and thin, harpsichord-like strings. It has a much lighter case construction than the modern piano and, except for later examples of the early nineteenth century (already evolving towards the modern piano), it has no metal frame or bracing. The action and hammers are lighter, giving rise to a much lighter touch, which in good fortepianos is also very responsive.

The range of the fortepiano was about four octaves at the time of its invention and gradually increased. Mozart (1756-1791) wrote his piano music for instruments of about five octaves. The piano works of Beethoven (1770-1827) reflect a gradually expanding range; his last piano compositions are for an instrument of about six octaves. (The range of most modern pianos, attained in the 19th century, is 7⅓ octaves.)

Fortepianos from the start had devices similar to the pedals of modern pianos; but these were not always pedals: sometimes hand stops or knee levers were used instead.

[edit] The sound of the fortepiano

Like the modern piano, the fortepiano can vary the sound volume of each note, depending on the player's touch. The tone of the fortepiano is quite different from that of the modern piano, being softer with less sustain. Sforzando accents tend to stand out more than on the modern piano, as they differ from softer notes in timbre as well as volume, and decay rapidly.

Fortepianos also tend to have quite different tone quality in their different registers--noble and slightly buzzing in the bass, "tinkling" in the high treble, and more rounded (closest to the modern piano) in the mid range. In comparison, modern pianos are rather more uniform in sound through their range.

[edit] History

[edit] Cristofori

What we now call the fortepiano was invented by the harpsichord maker Bartolomeo Cristofori in Florence around the turn of the 18th century. The first reliable record of a fortepiano appears in the inventory of the Medici family (who were Cristofori's patrons), dated 1700. Cristofori continued to develop the instrument until the 1720's, the time from which the surviving three Cristofori instruments date.

Cristofori is perhaps best admired today for his ingenious fortepiano action, which in some ways was more subtle and effective than that of many later instruments. However, other innovations were also needed to make the fortepiano possible. Merely attaching the Cristofori action to a harpsichord would have produced a very weak tone. Cristofori's instruments instead used thicker, tenser strings, mounted on a frame considerably more robust than that of contemporary harpsichords. As with all later pianos, in Cristofori's instruments the hammers struck more than one string at a time; Cristofori used pairs of strings throughout the range.

Cristofori was also the first to incorporate a form of soft pedal into a piano (the mechanism by which the hammers are made to strike fewer than the maximum number of strings; Cristofori's was a hand stop). It is not clear whether the modern soft pedal descends directly from Cristofori's work or arose independently.

[edit] The early spread of the fortepiano

Cristofori's invention soon attracted public attention as the result of a journal article written by Scipione Maffei and published 1711 in Giornale de'letterati d'Italia of Venice. The article included a diagram of the action, the core of Cristofori's invention. This article was republished 1719 in a volume of Maffei's work, and then in a German translation (1725) in Johann Mattheson's Critica Musica. The latter publication was perhaps the triggering event in the spread of the fortepiano to German-speaking countries.

Cristofori's instrument spread at first quite slowly, probably because, being more elaborate and harder to build than a harpsichord, it was very expensive. For a time, the fortepiano was the instrument of royalty, with Cristofori-built or -styled instruments played in the courts of Portugal and Spain. Several were owned by Queen Maria Barbara of Spain, who was the pupil of the composer Domenico Scarlatti. One of the first private individuals to own a fortepiano was the castrato Farinelli, who inherited one from Maria Barbara on her death.

The first music specifically written for fortepiano dates from this period, the Sonate da cimbalo di piano (1732) by Lodovico Giustini. This publication was an isolated phenomenon; James Parakilas (see reference below) conjectures that the publication was a meant as a honor for the composer on the part of his royal patrons. Certainly there could have been no commercial market for fortepiano music while the instrument continued to be an exotic specimen.

It appears that the fortepiano did not achieve full popularity until the 1760s, from which time the first records of public performances on the instrument are dated, and when music described as being for the fortepiano was first widely published.

[edit] Silbermann

It was Gottfried Silbermann who brought the construction of fortepianos to the German-speaking nations. Silbermann, who worked in Freiberg in Germany, began to make pianos based on Cristofori's design around 1730. (His previous experience had been in building organs, harpsichords, and clavichords.) Like Cristofori, Silbermann had royal support, in his case from Frederick the Great of Prussia, who bought many of his instruments.

Silbermann's instruments were famously criticized by Johann Sebastian Bach around 1736, but later instruments encountered by Bach in his Berlin visit of 1747 apparently met with the composer's approval. It has been conjectured (by James Parakilas; see References) that the improvement in Silbermann's instruments resulted from his having seen an actual Cristofori piano, rather than merely reading Scipione Maffei's article. The piano action Maffei described does not match that found in surviving Cristofori instruments, suggesting that Maffei either erred in his diagram (he admitted having made it from memory) or that Cristofori improved his action during the period following Maffei's article.

Silbermann is credited with the invention of the forerunner of the damper pedal, which removes the dampers from all the strings at once, permitting them to vibrate freely. Silbermann's device was in fact only a hand stop, and thus could be changed only at a pause in the music. Throughout the Classical era, even when the more flexible knee levers or pedals had been installed, the lifting of all the dampers was used primarily as a coloristic device. In the post-fortepiano era of the 19th century, the damper pedal became the foundation of piano sound, which came to rely on the sympathetic vibrations of the undamped but unstruck strings.

[edit] The Viennese school

The fortepiano builders who followed Silbermann introduced actions that were simpler than the Cristofori action, even to the point of lacking an escapement (the device that permits the hammer to fall to rest position even when the key has been depressed). Such instruments were the subject of criticism (particularly, in a widely quoted 1777 letter from Mozart to his father), but were simple to make and were widely incorporated into square pianos.

One of the most distinguished fortepiano builders in the era following Silbermann was one of his pupils, Johann Andreas Stein, who worked in Augsburg, Germany. Stein's fortepianos had (what we, or Cristofori, would call) "backwards" hammers, with the striking end closer to the player than the hinged end. This action came to be called the "Viennese" action, and was widely used in Vienna, even on pianos up to the mid 19th century. The Viennese action was simpler than the Cristofori action, and very sensitive to the player's touch. According to Edwin M. Ripin (see references below), the force needed to depress a key on a Viennese fortepiano was only about fourth of what it is on a modern piano, and the descent of the key only about half as much. Thus playing the Viennese fortepiano involved nothing like the athleticism exercised by modern piano virtuosos, but did require exquisite sensitivity of touch.

Stein put the wood used in his instruments through a very severe weathering process, and this included the generation of cracks in the wood, into which he would then insert wedges. This gave his instruments a considerable longevity, on which Mozart commented, and there are several instruments still surviving today.

Another important Viennese builder was Anton Walter, a friend of Mozart's who built instruments with a somewhat more powerful sound than Stein's. Although Mozart admired the Stein fortepianos very much, as the 1777 letter mentioned above makes clear, his own piano was a Walter.

The fortepianos of Stein and Walter are widely used today as models for the construction of new fortepianos, discussed below.

Stein's fortepiano business was carried on in Vienna with distinction by his daughter Nannette Streicher along with her husband Johann Andreas Streicher. The two were friends of Beethoven, and one of the composer's pianos was a Streicher.

Later on in the early 19th century, more robust instruments with greater range were built in Vienna, by (for example) the Streicher firm, which continued through two more generations of Streichers. Another important builder in this period was by Conrad Graf, who made Beethoven's last piano. Graf was one of the first Viennese makers to build pianos in quantity, as a large business enterprise.

[edit] The fortepiano in England

The English fortepiano had a humble origin in the work of Johann Christoph Zumpe, a maker who had immigrated from Germany and worked for a while in the workshop of the great harpsichord maker Burkat Shudi. Starting in the middle to late 1760's, Zumpe made inexpensive square pianos that had a very simple action, lacking an escapement,(sometimes known as the 'old mans head'). Although hardly a technological advancement in the fortepiano, Zumpe's instruments proved very popular (they were imitated outside of England), and played a major role in the displacement of the harpsichord by the fortepiano. These square pianos were also the medium of the first public performances on the instrument in the 1760s, notably by Johann Christian Bach.

Later work showed that Zumpe's simple action could be augmented with an escapement. This was the origin of the English action, the work of three Shudi employees, John Broadwood, Robert Stodart, and Americus Backers. The English action enabled a louder, more robust sound than the Viennese one, though it required deeper touch and was less sensitive. The early English grand pianos by these builders physically resembled Shudi harpsichords; which is to say, very imposing, with elegant, restrained veneer work on the exterior. Unlike contemporary Viennese instruments, English grand fortepianos had three strings rather than two per note.

John Broadwood married the master's daughter (Barbara Shudi, 1769) and ultimately took over and renamed the Shudi firm. The Broadwood company (which survives to this day, [1]), was an important innovator in the evolution of the fortepiano into the piano. It shipped a piano to Beethoven in Vienna, which the composer evidently treasured.

[edit] Obsolescence and revival

From the late 18th century, the fortepiano underwent extensive technological development and thus evolved into the modern piano; for details, see Piano. The older type of instrument ceased to be made.

In the late 19th century, the early music pioneer Arnold Dolmetsch built three fortepianos. However, this attempted revival of the fortepiano was evidently several decades ahead of its time, and did not lead to widespread adoption of the instrument.

It was only in the latter half of the 20th century that the fortepiano was effectively revived, as part of the authentic performance movement that began in that era and continues to this day. Old fortepianos were restored, and new ones were built along the lines of the old. This revival closely resembled the 20th century revival of the harpsichord, though occurring somewhat later in time. Among the more prominent modern builders have been Philip Belt, Paul McNulty, and Rodney Regier. As with harpsichords, fortepianos are sometimes built from kits purchased from expert makers (1, 2).

The reintroduction of the fortepiano has permitted performance of 18th and early 19th century music on the instruments for which it was written, yielding new insights into this music; for detailed discussion, see Piano.

A number of modern pianists have achieved distinction in fortepiano performance, including Malcolm Bilson, Robert Levin, Trevor Pinnock, Steven Lubin, Gustav Leonhardt, Geoffrey Lancaster, Bart van Oort and Jörg Demus.

[edit] Opinions about the fortepiano

People's opinions about fortepiano sound vary widely, both from person to person and from instrument to instrument. Here are three representative opinions about fortepianos:

Although I am a lover of performances on authentic instruments the fortepiano was one of the least successful instruments and the most deserving of improvement. I am not always comfortable with the sound made by many fortepianos and however fine a performance may be I find it difficult at times to get past the often unpleasant sound.

--Michael Cookson

A frequent initial reaction to the sound of the fortepiano is that it is less beautiful than that of a fine modern concert grand piano. I believe that such a reaction will usually be changed if the player listens to good recordings. The clear sound and relatively short sustain of the fortepiano tends to favor the special elements of style in the music of Haydn and Mozart. The sound is different but not inferior.

--Howland Auchincloss

This reproduction of a 1730 Cristofori - the greatest of all makers and often the most underrated - by Denzil Wraight based on one made for Scarlatti’s patron Queen Maria Barbara of Spain makes a gorgeous sound. Yes it can be metallic and subdued in climaxes but it has a marvellous delicacy and, especially in the expressive sonatas, a profoundly beautiful sound.

--Gary Higginson

[edit] Etymology and usage

"Fortepiano" is Italian for "loud-soft", just as the formal name for the modern piano, "pianoforte", is "soft-loud". Both are abbreviations of Cristofori's original name for his invention: gravecembalo col (or di) piano e forte, "harpsichord with soft and loud".

The term fortepiano is somewhat specialist in its connotations, and does not preclude using the more general term piano to designate the same instrument. Thus, usages like "Cristofori invented the piano" or "Mozart's piano concertos" are currently common and would probably be considered acceptable by most musicians. Fortepiano is used in contexts where it is important to make the precise identity of the instrument clear, as in (for instance) "a fortepiano recital by Malcolm Bilson". For further discussion see 1.

In fact, the use of "fortepiano" specifically to refer to early pianos appears to be recent. Even the authoritative Oxford English Dictionary does not record this usage, noting only that "fortepiano" is "an early name of the pianoforte". During the age of the fortepiano, "fortepiano" and "pianoforte" were used interchangeably, as the OED's attestations show.

Jane Austen, who lived in the age of the fortepiano, used "pianoforte" (also: "piano-forte", "piano forte") for the many occurrences of the instrument in her work.

The other meaning of fortepiano - the musical term, as mentioned at the top of this page - obviously derives from the same Italian.
