Want to transform your piano playing? Start with mastering the pedals. The sustain pedal (right) and una corda pedal (left) are key tools for shaping sound and adding emotion. Here’s how they differ:
- Sustain Pedal: Lifts all dampers, letting notes resonate longer and creating rich harmonics. Ideal for smooth legato, lush textures, and classical to jazz transitions.
- Una Corda Pedal: Shifts the hammer to strike fewer strings, softening the tone. Perfect for delicate dynamics, tonal variations, and quiet passages.
Quick Comparison
| Feature | Sustain Pedal | Una Corda Pedal |
|---|---|---|
| Function | Lifts all dampers | Moves hammer sideways |
| Sound Effect | Extends note resonance | Softens and changes tone |
| Dynamic Impact | Full volume range | Lowers max volume |
| String Contact | Affects all strings | Strikes fewer strings |
Pro Tip: Use them together for rich, atmospheric effects in pieces like Debussy’s Clair de Lune. Timing and practice are key to unlocking their full potential.
The Sustain Pedal
How It Works
The sustain pedal changes the way a piano sounds by lifting the dampers off the strings. When you press it, the strings vibrate freely, letting the sound linger and creating harmonics and resonance even after you release the keys. This works through a lever system that connects the pedal to the damper rail, which manages the dampers across the piano’s range. In modern grand pianos, this also allows strings to interact through sympathetic resonance, adding depth and complexity to the sound.
History and Evolution
The sustain pedal traces back to the early 1700s with Bartolomeo Cristofori‘s first pianofortes. Early players used knee levers or hand stops to sustain notes. By the late 1700s, the foot pedal we recognize today was introduced and became standard in the early 19th century. This change allowed pianists to sustain notes while keeping their hands free, greatly expanding the piano’s expressive potential. Composers like Mozart and Chopin took full advantage of this, weaving sustained passages into their music.
How It’s Used Today
The sustain pedal continues to play a key role in music, offering a range of techniques:
- Full pedaling: Creates maximum resonance, perfect for rich, Romantic-era textures.
- Half pedaling: Offers subtle control over overtones, ideal for nuanced phrasing.
- Flutter pedaling: Produces light, delicate sustained effects.
Its use depends on the style of music. In classical pieces, it adds depth and texture, while in jazz, it helps create smooth transitions and enriches chord voicings. Contemporary musicians often experiment with it to achieve unique tonal effects. For Baroque music, its use is minimal, but in impressionistic works, it’s used extensively. Modern playing focuses on mastering the pedal’s timing and depth to enhance expression.
The Una Corda Pedal
How It Works
The una corda pedal changes the way the piano hammers interact with the strings. On grand pianos, pressing this pedal shifts the hammer assembly slightly to the right. This adjustment makes the hammers strike fewer strings and hit a less-worn part of the felt, producing a softer and more delicate tone.
Origins and Development
Bartolomeo Cristofori, the inventor of the early pianoforte, introduced the una corda pedal in 1722. Back then, it allowed the hammers to hit just one string (the term una corda translates to "one string" in Italian), creating a much more dramatic effect than what we hear today.
During the 19th century, piano makers refined the mechanism significantly. By 1830, manufacturers like Érard and Broadwood had standardized the shifting action seen in modern grand pianos. These advancements laid the groundwork for its use in a wide range of musical performances.
Uses in Performance
The una corda pedal greatly expands a pianist’s ability to shape sound. It’s especially important in Classical repertoire, where composers like Beethoven often included specific markings for its use. For example, his Piano Sonata No. 28 in A Major, Op. 101 includes instructions for "una corda" (one string) and "tre corde" (three strings).
Here are some key ways pianists use the una corda pedal:
- To achieve extremely soft dynamics for quiet passages
- To add subtle tonal variations within a phrase
- To create special sound effects that stand out
In large concert halls, pianists tend to use it sparingly, but in smaller venues or recording studios, it becomes indispensable for precise tonal control. Many professionals combine the una corda with the damper pedal to enhance expressiveness, particularly in Romantic and Impressionist works. This technique produces an atmospheric sound that’s perfect for pieces by composers like Debussy and Ravel.

Pedal Differences and Uses
Technical Specifications
The sustain and una corda pedals have different mechanical designs and sound effects. Here’s a side-by-side look at their key features:
| Feature | Sustain Pedal | Una Corda Pedal |
|---|---|---|
| Primary Function | Lifts all dampers from strings | Moves hammer mechanism sideways |
| Sound Effect | Lets strings vibrate freely | Lowers volume and changes tone |
| String Contact | Affects all 88 keys | Strikes fewer strings |
| Mechanical Impact | No hammer movement | Shifts the hammer assembly |
| Sound Duration | Extends note length | No impact on duration |
| Dynamic Range | Maintains full range | Lowers maximum volume |
| Hammer Wear | Standard wear pattern | Hits less-used felt areas |
These differences shape how each pedal influences a pianist’s performance, as explained below.
Performance Effects
Using these pedals together or separately allows pianists to explore a wider range of expression. The sustain pedal primarily enhances note length and harmonic richness, enabling smooth transitions and lush textures.
The una corda pedal focuses on changing tone rather than sustain. Its sideways hammer movement results in three key effects:
- Creates softer dynamics not achievable with the sustain pedal
- Produces a gentler, muted tone
- Adds contrast between standard and quieter passages
When used together, these pedals offer even greater versatility. For example, combining them can be especially effective in soft, sustained sections that demand both extended harmonies and subtle tonal changes. This technique is often employed in pieces like Debussy’s Clair de Lune, where the delicate atmosphere and extended harmonies are crucial to the interpretation.
Mastering these pedals helps pianists make thoughtful decisions based on factors such as:
- Musical style and era
- Room acoustics
- Performance needs
- Composer’s directions
- Personal artistic choices
These considerations guide how and when to use each pedal for maximum impact.
How Do the Piano Pedals Work? [Quick Guide!] 🎹
Using Piano Pedals Effectively
Mastering piano pedals – through techniques like half-pedaling and tonal adjustments – can greatly enhance performance. The key lies in understanding the piano’s response and tailoring your pedaling to fit the music’s style.
Half-pedaling is essential for achieving varied sustain and clear articulation. For pieces with quick harmonic shifts, try syncopated pedaling – lift the pedal briefly after striking the notes for cleaner transitions.
The una corda pedal is a great tool for creating tonal variations. Use it sparingly to add subtle nuances, particularly in:
- Romantic-era music with dynamic contrasts
- Impressionist compositions focusing on tone and color
- Quiet passages where a distinct character shift is needed
To use both pedals effectively, practice slowly to refine timing and coordination. Gradually increase speed as you gain comfort and control.
