The Evolution of Piano Pedalling

A brief history of piano pedals 

The earliest pianos featured as few as one modifying mechanism, with some models boasting six or more stops. These early controls, operated by hand, were cumbersome, often requiring an assistant. By the late 18th century, knee levers replaced hand stops, making pedal use more accessible. The invention of foot pedals in the 19th century marked a turning point, leading to the configuration we know today. 

 

Key developments in piano pedalling 

1. The damper pedal: The soul of the piano 

Located on the right, the damper pedal is the most frequently used. It lifts all dampers from the strings, allowing them to vibrate freely even after the keys are released. This creates a rich, resonant sound and enables smooth, legato phrasing. Often called the "soul of the piano," the damper pedal is essential for creating expressive depth in music. 

 

2. The soft pedal: una corda and timbral magic 

Invented by Bartolomeo Cristofori, the soft pedal modifies the piano's timbre, not just its volume. On modern pianos, it shifts the hammers so fewer strings are struck, producing a subtle, ethereal tone. Historical pianos allowed even greater tonal variation, as pianists could select whether one, two, or three strings were struck per note. 

 

3. The sostenuto pedal: precision sustaining 

A 19th-century innovation, the sostenuto pedal allows specific notes or chords to sustain while others remain unaffected. This selective sustain is invaluable for complex compositions, transcriptions, and contemporary music. Although rare on upright pianos, it remains a standard feature on high-end grands. 

 

Lesser-known and historical pedals 

Piano builders of the past experimented with a range of pedals to enhance the instrument’s capabilities: 

• Moderator pedal: Introduced a layer of felt for a muted, dulcet tone. 

• Bassoon pedal: Created a buzzing effect reminiscent of a bassoon. 

• Janissary pedal: Imitated Turkish military bands with drums, cymbals, and bells. 

• Lute stop: Produced a pizzicato-like sound by damping the strings. 

Though fascinating, these novelty pedals eventually fell out of favor, leaving the modern piano with its streamlined design. 

 

Modern innovations 

Some contemporary piano models push the boundaries of pedal functionality. The Fazioli F308, for example, includes a fourth pedal that reduces volume without altering tone. Digital pianos also mimic pedal effects, offering advanced features like silent practice modes and programmable sostenuto. 

 

The role of pedals in piano performance 

Piano pedals are often seen as technical features, essential for achieving smooth transitions between notes or sustaining sound. However, their significance extends far beyond mere mechanics; they are powerful artistic tools that shape the emotional depth and expressiveness of a performance. The careful and intentional use of pedals allows pianists to give their interpretation a unique voice, enhancing the tone, texture, and overall atmosphere of the music.

Historically, composers have relied on the piano pedals to bring their compositions to life in ways that words alone could not. For instance, Beethoven’s strategic use of the una corda (soft pedal) and tre corde (the return of the normal pedal position) in his concertos creates a rich contrast between delicate, muted passages and powerful, full-bodied moments. This dynamic range captures the intense emotional shifts within his music, which would be far less impactful without the careful manipulation of the pedals.

As music evolved, composers continued to experiment with pedal techniques, adding new layers of complexity to piano performance. In modern and contemporary works, the sostenuto pedal, which sustains only the notes held down at the time of activation, allows for a more controlled and selective use of the sustaining effect. This enables pianists to create intricate textures, sustaining certain notes or harmonies while leaving others untouched, adding a unique sonic landscape to the music.

Pedals are also integral to shaping the overall tonal palette of the instrument. The damper pedal, perhaps the most widely used, creates a sense of resonance and continuity, often blurring the lines between chords and melodies. This effect is crucial in creating legato phrasing and rich harmonies, particularly in genres like romantic and impressionistic music. Meanwhile, the una corda pedal, which shifts the hammer slightly to strike only one of the three strings, produces a softer, more intimate sound. This subtle nuance can completely transform a passage, adding delicate shading or an ethereal quality.

 

Mastering piano pedals 

Mastering piano pedals is a fundamental skill that can significantly enhance your musical performance and expression. The proper use of pedals is essential for pianists of all levels, whether you're a beginner learning to create smooth, uninterrupted legato or an advanced player experimenting with a wide array of tonal colours and dynamics. 

The three pedals on a standard piano—the sustain (right), soft (left), and sostenuto (middle) - each have unique functions that allow you to shape your sound in different ways.  

The sustain pedal, for example, enables the pianist to connect notes and create a rich, resonant sound by holding the strings in vibration even after the keys are released. The soft pedal is typically used to lower the volume and produce a more delicate sound, helps create subtle nuances and contrasts, allowing the performer to vary the intensity of their playing. Finally, the sostenuto pedal is often the least understood but incredibly versatile, allows you to sustain specific notes or chords while still playing others without sustaining them. 

Learning to coordinate and blend the use of these pedals can unlock the piano’s full expressive potential, allowing you to control the texture, resonance, and articulation of the music. With practise, you can develop a deeper understanding of the emotional range and subtlety that pedal use can bring to a piece, from creating ethereal, dreamlike effects to adding dramatic flair to fast passages.
