Chang began his passion for jazz at Castillero Middle School. At the age of 13, Chang began accompanying nearby Pioneer High School with their daily musical rehearsals as well as a local dance studio. When Chang attended Pioneer High School, he soon received local recognition for his playing,[3] and by his senior year he had recorded an independent "senior project". The CD included original compositions and was sold locally to recoup recording expenses. Later that year Chang was selected as one of two pianists to the San Francisco High School Grammy Band.[4]
After graduating from USC's Thornton School of Music, Chang was discovered and asked to audition for an up-and-coming artist, Michael Bublé. Since 2003, Chang has been Bublé's musical director and pianist, traveling the world to sold-out shows, radio, and television appearances.[3] In 2023, he released the single "Love As A Weapon," which he wrote with his fiancée, musician Alex Lilly.[5]
In a 2023 interview, when asked about the importance of diversity in the entertainment industry, Chang stated: "If a Chinese boy, say me, doesn't see many Chinese men in music/film/television, I probably wouldn't pursue a career in those fields."[6]
On November 15, 2011, Chang produced and released the inspirational holiday album "Cold December Night." The album features "melancholy interpretations of Christmas songs envisioned by various members of Michael Bublé's touring band."
In addition to his writing credentials with Michael Bublé, Chang co-wrote two tracks with singer Josh Kelley on his album To Remember: "Walk Right In" and "More Than Love". Chang also co-wrote "Stargazing" for X Factor champion Leon Jackson. The track is on his debut album Right Now. Chang has also co-wrote "Giant" from The Voice (US)" Season 1 winner Javier Colon's album Gravity.
Chang is also a member of the Los Angeles-area rock band formerly known as The Cosmic Giggle[3] and The Good Night; it is currently known as Your Future Lovers.
