An electric piano is a musical instrument that produces sound using electronic means rather than traditional strings or hammers. It typically features a keyboard similar to an acoustic piano but generates sound through electronic circuits and speakers. Electric pianos can mimic the sound of acoustic pianos and other instruments, making them versatile for various music styles. Many electric pianos come with built-in features like rhythm patterns, recording capabilities, and different instrument sounds. They are often lighter and more portable than acoustic pianos, making them popular for both home use and live performances. Some well-known brands include Yamaha, Roland, and Korg.
