1. Mozart’s Walter Fortepiano
Piano Characteristics
Anton Walter, a prominent piano maker in Vienna, transformed fortepiano design during the late 18th century [2]. Mozart purchased his own Walter fortepiano around 1782 [2].
This instrument introduced several notable features. Its straight-strung design ensured that each note resonated independently [4]. It had a range of 5.5 octaves (from FF to g”’) [1], and its hammer heads were covered in thin leather, rather than felt, giving it a sharper and more defined sound [4].
| Feature | Walter Fortepiano | Modern Piano |
|---|---|---|
| Weight | 95 kg (210 pounds) | 400–475 kg (880–1,045 pounds) |
| Key Touch | 10× lighter | Heavier resistance |
| Hammer Weight | ~5 grams | 30+ grams |
| Sound Decay | Immediate and rapid | Gradual swell then decay |
These unique characteristics had a direct influence on Mozart’s compositions.
Impact on Compositions
The Walter fortepiano’s design not only set it apart acoustically but also shaped how Mozart wrote his music. Each register had its own tonal identity: a clear and piano-like middle range, bright upper notes, and a resonant, textured bass [4]. This allowed Mozart to add layers of expression and detail to his musical storytelling.
"One writes for acoustical and aesthetic properties of the instruments at hand." – Robert Levin [6]
The fortepiano’s light touch and quick sound decay gave Mozart control over intricate phrasing and accents [5]. Knee levers, an early form of the modern damper pedal [2], added another dimension to his expressive capabilities.
Notable Works
The Walter fortepiano played a key role in some of Mozart’s most celebrated works. Between 1785 and 1791, he composed over 50 pieces on this instrument [6]. It was central to the creation and debut performances of his later piano concertos [7].
Today, only about twenty pianos of this type survive, and very few are still playable [2]. Musicians and researchers study these instruments to gain insight into Mozart’s musical vision. Pianist Robert Levin, for example, has recorded Mozart’s piano sonatas using the composer’s original Walter fortepiano [6].
2. Beethoven’s 1817 Broadwood
Piano Characteristics
Beethoven’s musical needs went beyond the delicate touch favored by Mozart. He needed an instrument with more power, and the English-made Broadwood piano delivered. Unlike the lighter Viennese pianos, this model featured a sturdier build, allowing for higher string tension and a louder, more resonant sound [8]. It also came equipped with a 6-octave keyboard and included design updates like a repositioned wrest plank at the back of the case and a pedal system that replaced the older hand stops [9].
| Feature | Specification | Impact |
|---|---|---|
| Keyboard Range | 6 octaves | Expanded creative possibilities |
| Pedal System | Split sustain pedal | Separate control of bass and treble sustain |
| Construction | Reinforced frame | Allowed for greater string tension and volume |
| Original Cost | £71.8.0 (£78.16.6 shipped) | Positioned as a high-end instrument of its era |
Impact on Compositions
The Broadwood piano reached Vienna in early 1818, during a challenging period for Beethoven as his deafness worsened. Dr. Alastair Laurence, Chairman of Broadwood, sheds light on its significance:
"Thomas Broadwood was trying to help Beethoven cope with his deafness. And the English piano is considerably louder in volume when compared with the Viennese equivalents. So I think that was Thomas’ thinking, to give him a piano that could help him." [11]
The split sustain pedal was a game-changer, giving Beethoven the ability to control bass and treble independently. This feature opened up new tonal possibilities, enabling him to experiment and push boundaries even as his hearing deteriorated [11][10]. With his ‘inner ear’ as a guide, Beethoven continued to compose works that reflected his evolving style [10].
Notable Works
Beethoven’s Broadwood piano became a catalyst for his later masterpieces. One standout is the final movement of the "Hammerklavier" Sonata, which he composed on this very instrument [11]. Deeply moved by the gift, Beethoven expressed his gratitude in a letter to Thomas Broadwood:
"I have never felt a greater pleasure than your honour’s intimation of the arrival of this piano, with which you are honouring me as a present. I shall look upon it as an altar upon which I shall place the most beautiful offerings of my spirit to the divine Apollo." [8]
Beethoven’s intense playing style even caused the strings to snap, described by Johann Andreas Stumpff as being "mixed up like a thorn bush in a gale" [8]. Today, this historic piano is housed in Hungary’s National Museum, serving as a powerful reminder of its role in Beethoven’s legacy [11].
3. Chopin’s Preferred Pleyels
Piano Characteristics
Pleyel pianos stood out for their distinct tonal qualities, divided into three sections: a bright, silvery high register, a rich midrange, and a clear, powerful bass [12].
| Feature | Specification | Impact on Performance |
|---|---|---|
| Key Size | Smaller than modern pianos | Allowed for greater control and precision |
| Key Depth | 8mm (vs. 10mm modern) | Enabled faster, more expressive playing |
| Action Weight | Lighter than contemporaries | Made delicate passages easier to execute |
| Octave Span | Narrower than modern pianos | Improved comfort for complex fingering |
| Sound Projection | More intimate | Perfect for smaller, salon-style performances |
Impact on Compositions
The Pleyel’s lighter action and responsive touch had a direct influence on Chopin’s playing and composing style. Its tonal variety offered a palette of expressive possibilities. Piano expert Marcel Lapointe explained that, unlike modern pianos with more uniform sound, the Pleyel provided "many different colors with which to work" [12].
Renowned pianist Hubert Rutkowski commented on the instrument’s sensitivity:
"This instrument is highly sensitive to the smallest detail […] one might get the impression of a direct contact with the strings" [13].
Chopin himself acknowledged the special connection he felt with Pleyel pianos:
"When I feel out of sorts, I play on an Érard piano where I easily find a ready-made tone. But when I feel in good form, and strong enough to find my own individual sound, then I need a Pleyel piano." – Frédéric Chopin [13]
This close bond between Chopin and the Pleyel piano played a crucial role in shaping his creative process and compositions.
Notable Works
Chopin’s relationship with Pleyel pianos was deeply intertwined with his artistic journey. His first Paris concert in 1832 featured a Pleyel instrument, marking the beginning of a lifelong association [14]. Each summer, he ensured a Pleyel grand was delivered to him [14].
One of his most memorable moments came during his final Paris concert on February 16, 1848, at Salle Pleyel. This event included the debut public performances of:
- The Barcarolle, Op.60
- The Cello Sonata, Op.65 [15]
Chopin also brought his personal Pleyel piano to his London debut, showcasing its "slightly veiled sonority" [14]. This particular instrument, listed as number 13819 in Pleyel’s records, was valued at 2,200 francs [15]. These instruments were not just tools for Chopin – they were integral to his legacy.

4. Liszt’s Custom Instruments
Liszt had a unique approach to pianos. While Mozart prioritized clarity and Beethoven sought volume, Liszt demanded instruments that could handle his fiery playing style and intense energy.
Piano Characteristics
Liszt’s vigorous technique was too much for the delicate Pleyels favored by Chopin. His powerful performances often broke strings and hammers, pushing piano manufacturers to reinforce their designs specifically for his needs [18].
| Feature | Specification | Purpose |
|---|---|---|
| Action | Light touch mechanism | Allowed faster passages and repeated notes |
| Bass | Enhanced resonance | Produced richer, deeper tones |
| Construction | 80% spruce tone wood | Improved resonance and durability |
| Strings | Steel core with copper layers | Added strength and tonal depth |
Bösendorfer even developed a special resonance case, making the entire piano body act as a soundboard to enhance sustain and tone [18].
Impact on Compositions
These piano innovations influenced Liszt’s music. For example, the sostenuto pedal on his 1883 Steinway grand allowed him to rework pieces like Consolation No. 3 and his transcription of Berlioz’s work [16]. This pedal expanded his tonal range and reinforced his reputation as a trailblazer in piano performance.
Liszt also built strong relationships with piano makers. He praised Steinway’s craftsmanship, saying:
"The new Steinway grand is a glorious masterpiece in power, sonority, singing quality and perfect harmonic effects, affording delight even to my old piano-weary fingers." [19]
His admiration for Bösendorfer was equally effusive:
"The perfection of a Bösendorfer exceeds my wildest expectations." [18]
These advancements in piano technology were key to his groundbreaking performances.
Notable Works
Liszt’s reliance on yearly updates from makers like Bechstein and decades of use of his Boisselot piano highlight how integral these instruments were to his artistry [16][19]. His connection with Bösendorfer is well-documented, with over 40 letters and telegrams exchanged between them [18]. In 1877, Liszt even performed on Wagner’s Steinway "Centennial" grand piano during the opera house inauguration [16].
Rachmaninoff once said:
"If the word personality didn’t exist, it would be invented only for Franz Liszt." [17]
Piano Comparison
This section examines the differences between the pianos used by Mozart and Beethoven, highlighting how advancements in piano design influenced sound and musical expression over time.
Design and Construction Features
Here’s a side-by-side look at Mozart’s Walter fortepiano and Beethoven’s 1817 Broadwood:
| Feature | Mozart’s Walter Fortepiano (Replica) | Beethoven’s 1817 Broadwood |
|---|---|---|
| Key Range | F1–g3 (5 octaves plus 1 note)[3] | 6 octaves[8] |
| Action Mechanism | Viennese action mechanism[3] | English grand action[8] |
| Materials | Ebony naturals and bone sharps[3] | Spanish mahogany case[20] |
| Unique Features | Two knee levers (forte, moderator)[3] | Enhanced string tension[8] |
These design differences shaped how each instrument sounded and responded to a player’s touch.
Sound Characteristics
Mozart’s fortepiano was known for its clear, crisp sound, particularly in the lower registers, which brought out the intricate patterns of Alberti bass passages[22]. Beethoven’s Broadwood, on the other hand, was built for power. According to Dr. Alastair Laurence, Chairman of Broadwood:
"Thomas Broadwood was trying to help Beethoven cope with his deafness. And the English piano is considerably louder in volume when compared with the Viennese equivalents. So I think that was Thomas’ thinking, to give him a piano that could help him." [11]
This increased volume and resonance made the Broadwood better suited for Beethoven’s dramatic and expressive music.
Historical Significance
These instruments reflect pivotal moments in piano evolution. English innovations led to deeper resonance and greater dynamic possibilities[21]. Such developments not only expanded the piano’s capabilities but also influenced how composers wrote music for the instrument.
Performance Implications
The delicate clarity of the fortepiano contrasts sharply with the dynamic range of modern pianos. Performers today must adjust their interpretations to honor the original sound of historical instruments while working with the broader tonal palette of contemporary pianos. This balance is key to capturing the essence of classical compositions.
Summary
The Classical and Romantic periods saw a transformation in piano design and music composition. Between 1800 and 1820, the number of piano manufacturers in Vienna grew from 10 to 50, highlighting the rising demand for more advanced instruments [24].
Composers and piano makers worked closely, pushing the boundaries of what the instrument could do. As Jan Swafford explains:
"What Beethoven wanted from pianos, as he wanted from everything, was more: more robust build, more fullness of sound, a bigger range of volume, a wider range of notes. As soon as new notes were added to either end of the keyboard, he used them, making them necessary to anyone wanting to play his work." [23]
Responding to these challenges, piano makers introduced key improvements. By the time of Beethoven’s death, features like the seven-octave keyboard, double-escapement action, and metal frames had become standard [24]. Modern pianos, in contrast to early fortepianos, now endure frame pressures ranging from 18 to 30 tons [25].
The lighter, more transparent sound of Viennese pianos and the robust, resonant tone of English Broadwoods influenced composers’ styles [21]. Concert pianist Ronald Brautigam captures the significance of this relationship:
"Beethoven’s status among piano builders was enormous, so to please him was to please the world." [24]
The shift from early fortepianos to modern pianos reflects a blend of artistic vision and technical progress, reshaping music forever.
