What is sustain pedal?

A sustain pedal is a foot-operated pedal used by piano and keyboard players to sustain the sound of the notes played after the keys are released. When the sustain pedal is pressed down, it lifts the dampers off the strings, allowing the strings to vibrate freely and sustain the sound.

Sustain pedals are commonly used in a variety of musical genres, from classical music to pop and rock. They are an essential tool for creating a smooth and connected sound, especially when playing pieces with long, sustained notes or chords.

There are different types of sustain pedals available, including traditional piano-style pedals and more compact, portable models for keyboards and MIDI controllers. Some sustain pedals also offer additional features such as polarity switching, adjustable pedal sensitivity, and half-pedaling capabilities.

Overall, the sustain pedal is a versatile and essential accessory for pianists and keyboard players looking to enhance their playing and expressiveness.
