At the age of 6, Jony C a.k.a. Jonathan Cheung, started piano lessons and singing in children's choir. Perhaps it was his parents' push for him to learn music, or his vivid memory of his father coaching him to sing the song "Jesus loves me" the night before his first singing competition, ignited his interest in music. Over the years, he learned other instruments such as clarinet, percussion, saxophone, guitar, and bass. He liked performing different kinds of music with various groups including jazz band, symphony, punk rock band, etc. However, he did not think much about music as his profession.
