Understanding the Different Types of Piano Pedals and Their Uses

Piano pedals play a crucial role in shaping the sound and expression of the instrument. They provide pianists with additional control over the sustain, dynamics, and overall character of the music. In this article, we will explore the three primary pedals found on most pianos—the sustain pedal, the soft pedal, and the sostenuto pedal—and discuss their functions and how to use them effectively.

1. Sustain Pedal (Right Pedal)

The sustain pedal is the most commonly used pedal on the piano, located at the right side of the pedal unit. It is often referred to as the damper pedal. When pressed, the sustain pedal raises all the dampers inside the piano, allowing the strings to vibrate freely, resulting in a sustained sound even after releasing the keys.

How to Use the Sustain Pedal:

  • Standard Usage: Start by depressing the desired keys on the keyboard, and then press the sustain pedal with your right foot. This allows the notes to continue resonating while your hands are free to play new notes. Release the pedal to stop the sustain effect.
  • Partial Pedaling: Experiment with partial pedaling to achieve different tonal effects. Instead of fully depressing the pedal, try half-pedaling by pressing it halfway down. This allows for a more nuanced sustain, enabling certain notes to ring while others are slightly muted.
  • Pedal Switching: In more advanced pieces, you may encounter instances where you need to quickly switch between pedaling and releasing the pedal. Practice coordinating your pedal movements with your hands to achieve seamless transitions and avoid muddying the sound.

2. Soft Pedal (Left Pedal)

The soft pedal, also known as the una corda pedal or the left pedal, is located on the left side of the pedal unit. When pressed, it shifts the entire piano action, causing the hammers to strike fewer strings, resulting in a softer and more subdued sound.

How to Use the Soft Pedal:

  • Softening the Sound: Press the soft pedal with your left foot to engage it. The hammers will then shift, allowing them to strike only two of the three strings per note (in most modern pianos). This produces a mellow and quieter sound. Release the pedal to return to the standard playing position.
  • Half Pedaling: Similar to the sustain pedal, the soft pedal can also be half-pedaled to achieve varying degrees of softness. Experiment with partial pedaling to find the desired level of softness and tonal shading.

3. Sostenuto Pedal (Middle Pedal)

The sostenuto pedal is the least commonly used pedal and is often found on grand pianos. It is located in the middle of the pedal unit. When pressed, it sustains only the notes that are being played at the moment, while other notes played before or after are unaffected.

How to Use the Sostenuto Pedal:

  • Selective Sustain: Press the sostenuto pedal after playing the desired notes. The dampers of those specific notes will be lifted, allowing them to sustain, even if you release the keys. Other notes played after pressing the Sostenuto pedal will not be affected. Release the pedal to disengage the Sostenuto effect.
  • Releasing and Engaging the Pedal: Unlike the sustain pedal, which is usually engaged and released with each use, the sostenuto pedal is typically pressed down and remains engaged until intentionally released. Practice precise foot control to ensure the pedal is used only when necessary.

Note: It’s important to remember that not all pianos have a sostenuto pedal. It is more commonly found on higher-end grand pianos, while most upright pianos do not have a sostenuto pedal.


Understanding the different types of piano pedals and their uses is essential for pianists to fully express themselves and bring out the nuances of the music they play. The sustain pedal provides sustain and resonance, the soft pedal offers a softer sound, and the sostenuto pedal allows for selective sustain. By mastering the use of these pedals and experimenting with different techniques, pianists can add depth, expressiveness, and dynamics to their performances. Practice regularly and explore the possibilities that these pedals offer, unlocking new dimensions of musicality in your piano playing.
