The piano is a remarkable instrument known for its expressive capabilities, and much of this expressiveness comes from the use of its pedals. While many people focus on learning the keys, understanding how the pedals work is crucial for achieving a well-rounded and dynamic performance. Most modern acoustic pianos come with three pedals, each serving a distinct purpose. These pedals are the damper pedal (sustain pedal), the soft pedal (una corda), and the sostenuto pedal. Each one plays an essential role in shaping the sound, controlling dynamics, and adding depth to musical performances.
This article will provide a comprehensive explanation of what each piano pedal does, how to use them effectively, and the historical background behind their development. Whether you are a beginner or an experienced pianist, mastering the use of these pedals can take your playing to the next level.
1. The Damper Pedal (Sustain Pedal)
What Does the Damper Pedal Do?
The damper pedal, also called the sustain pedal, is the most frequently used pedal on a piano. It is the rightmost pedal and serves the primary function of sustaining sound by preventing the dampers from touching the strings.
When you press a piano key, a hammer strikes a string, producing sound. When you release the key, dampers (small felt-covered mechanisms) come down to stop the string’s vibration, silencing the note. However, when you press the damper pedal, these dampers lift, allowing the strings to continue vibrating even after you release the keys. This creates a sustained, resonant effect, allowing notes to blend together smoothly.
How to Use the Damper Pedal Effectively
Legato and Smooth Transitions: One of the primary reasons pianists use the damper pedal is to create legato passages (smoothly connected notes). Instead of playing choppy or disconnected phrases, the sustain pedal helps notes transition fluidly.
Harmonic Blending: When playing chords or melodies with harmony, using the damper pedal allows sounds to merge naturally, producing a fuller and richer tone.
Emphasizing Emotion: In expressive pieces, especially in romantic and classical music, the sustain pedal enhances depth and emotion, making melodies more lyrical.
Echo and Reverb Effects: In large concert halls, the sustain pedal can produce a reverberating effect, adding depth to a performance.
Common Mistakes When Using the Damper Pedal
Overuse of the Pedal: Beginners often make the mistake of holding the pedal down for too long, causing the sound to become muddy and unclear.
Not Changing the Pedal on Chord Changes: To avoid excessive overlap, it’s important to release and reapply the pedal when changing chords.
Using the Pedal as a Substitute for Finger Technique: The pedal should enhance playing, not replace proper finger movement.
Historical Background of the Damper Pedal
The damper pedal has evolved over centuries. Early pianos did not have a dedicated sustain mechanism, but composers such as Beethoven and Chopin incorporated the sustain pedal into their compositions, influencing how it is used today.
2. The Soft Pedal (Una Corda Pedal)
What Does the Soft Pedal Do?
The soft pedal, also known as the una corda pedal, is the leftmost pedal on a piano. It alters the sound by making it softer and more delicate. The term “una corda” means “one string” in Italian, referencing how this pedal originally worked on early pianos.
On a grand piano, pressing the soft pedal shifts the entire keyboard mechanism slightly to the right, causing the hammers to hit fewer strings. This produces a gentler and more muted sound.
On an upright piano, the soft pedal functions differently. Instead of shifting the mechanism, it moves the hammers closer to the strings, reducing their impact force, which results in a softer sound.
How to Use the Soft Pedal Effectively
Creating a Mellow Tone: This pedal is useful when playing soft or intimate pieces, especially in classical and jazz music.
Expressing Subtlety: Composers often mark pieces with “una corda” to indicate that the soft pedal should be used for greater nuance and contrast.
Reducing Volume Without Losing Clarity: Unlike simply playing softly with the fingers, the soft pedal provides consistent quietness without altering finger technique.
Common Mistakes When Using the Soft Pedal
Overuse in Fast Pieces: The soft pedal is best used in expressive, slower sections rather than in fast and powerful passages.
Relying on It Instead of Dynamics: Pianists should develop touch control rather than relying on the pedal for soft dynamics.
Historical Background of the Soft Pedal
The una corda pedal was first introduced by Bartolomeo Cristofori, the inventor of the piano. Early pianos had multiple strings per note, and shifting the hammers to hit fewer strings created a distinct tonal change.
3. The Sostenuto Pedal
What Does the Sostenuto Pedal Do?
The sostenuto pedal is the middle pedal on most grand pianos (though some upright pianos may lack it or replace it with a practice pedal). This pedal allows certain notes to be sustained while others remain unaffected.
When you press a key and then engage the sostenuto pedal, only those specific notes continue to ring, while other notes played afterward are not sustained. This provides a selective sustain, unlike the damper pedal, which lifts all the dampers.
How to Use the Sostenuto Pedal Effectively
Sustaining Bass Notes While Playing Melodies: One common use of the sostenuto pedal is to hold a bass note while playing free-moving melodies above it.
Controlling Harmony in Complex Passages: Some classical and jazz compositions require holding specific chords while allowing other notes to be played normally.
Blending Tones in Orchestral Piano Music: When imitating an orchestra or organ, the sostenuto pedal helps create sustained harmonies.
Common Mistakes When Using the Sostenuto Pedal
Confusing It With the Damper Pedal: Many beginners mistake the sostenuto pedal for the damper pedal, which can lead to improper sustain.
Not Using It in Suitable Repertoire: While useful, the sostenuto pedal is not commonly needed in most beginner and intermediate pieces.
Historical Background of the Sostenuto Pedal
The sostenuto pedal was introduced in the 19th century by the Steinway & Sons piano company. This addition gave pianists greater flexibility, but many compositions do not explicitly call for it, making it the least-used pedal.
Conclusion
Understanding how to use the three piano pedals—the damper pedal, soft pedal, and sostenuto pedal—can significantly enhance musical expression. The damper pedal provides sustain and resonance, the soft pedal allows for delicate and nuanced playing, and the sostenuto pedal offers selective sustain for greater control.
Each pedal serves a unique purpose, and mastering their use can transform a pianist’s playing style. Whether playing classical, jazz, or modern pieces, effective pedal control adds depth, texture, and emotion to music. By practicing proper technique and avoiding common mistakes, pianists can use these pedals to achieve a more professional and polished sound.
