His earliest training in piano came from watching his elder sister Yolande practice. She had decided she was going to learn the piano after finding a job which allowed her to save the required amount of money for buying an upright piano. Cziffra, who was weak as a child, often watched his sister practice, and mimicked her. He learned without sheet music, instead repeating and improvising over tunes sung by his parents. Later he earned money as a child improvising on popular music at a local circus.
