William Joseph is a pianist and recording artist from Phoenix, Arizona.
William Joseph won, at age 8, a full music scholarship provided by the Boys Club of America, enabling him to study piano with Russian pianist Stella Saperstein.
He was the first teacher hired by Piano Warehouse in Phoenix, Arizona and taught for the company Arizona Music Lessons later to be renamed Arizona Music Academy, for which he still performs short teaching periods.
In 2003, Joseph performed at a charity event in his hometown and bumped into David Foster, for whom he played. Foster was impressed, and they began collaborating, eventually writing several songs together that would appear on 2004's Within, Joseph's major-label debut. By this time, Joseph was signed under Foster's 143 Records, a sub-label of Reprise Records and Warner Bros. Records.
In August and September 2004, Joseph opened for Josh Groban's "Closer Tour," covering 12 cities in the US and Canada, giving 16 concerts. During November & December 2005, Joseph was the opening act for Clay Aiken's "Joyful Noise" tour, which covered 36 cities in the US and Canada, giving 40 concerts.
