Ko-Eun Yi was born and raised in Seoul, Korea. While no one in her family is a musician — her father is a consultant for start-up businesses and her mother spends significant time as a ­volunteer — her parents love music and there was always a lot of it in their home. When Ko-Eun’s brother, who is four years older, began piano lessons, three-year-old Ko-Eun was drawn to the piano, very curious about the “sound box” and amazed by the magic coming out of it. She said that even at that young age she could feel how the sound transformed the atmosphere of the room.
