William Motzing

He continued to teach theory, arranging, modern jazz history, improvisation and ensembles at the Sydney Conservatorium of Music, as he had done since 1971. After retiring in 2011, he returned to New York to live with the family of his son, William John Motzing Jr., while he battled symptoms of SDS including paralysis throughout the body. He died peacefully from complications of the disease on January 30, 2014.

William Motzing was misdiagnosed with Parkinson's Disease in 2008. In 2013, his neurologist re-diagnosed his condition as Shy–Drager syndrome (SDS). SDS is a rare, aggressive disease that halts all the major organs of the body, for which there is no known cure.

William Motzing had over 30 Australian film and TV soundtracks to his name, including Newsfront, (which opened the London Film Festival and was the first Australian film to screen at the New York Film Festival), Young Einstein (for which he won the Australian Film Institute (AFI) Award for best original music score and the APRA Music Award), The Return of Captain Invincible, starring Alan Arkin and Christopher Lee and The Quiet American (2002). He was nominated for five AFI awards.

From 1968 to 1971, Motzing also toured the world as sound designer for contemporary jazz-rock band Blood, Sweat & Tears through his job with the Clair Brothers (Audio). After visiting Australia with the group in 1971, he relocated there on January 25, 1972, to take positions as lecturer in the jazz program directed by fellow American Howie Smith at the New South Wales State Conservatorium of Music (now Sydney Conservatorium of Music) and later at the Australian Film and Television School.

In the 1970s and 1980s Motzing arranged and conducted strings and horns on many of Australia's chart-topping hits. These include Peter Allen's "I Still Call Australia Home", which was added to the National Film and Sound Archive's Sounds of Australia registry in 2013; Billy Field's "Bad Habits", the title track of Bad Habits (Billy Field album), the largest selling album in Australia in 1981 and for which he received a gold award at the 12th Tokyo Music Festival; Sherbet's "Howzat", reaching the top 5 of the UK charts and also entering the US Billboard Hot 100 chart; INXS's "The Swing";Jon English's Australian top 20 singles "Turn the Page" and "Hollywood Seven"; and albums for Air Supply and Billy Thorpe. In 2008 he arranged and conducted "Don't Wait Until Tomorrow" for Leo Sayer.

He played trombone in the Eastman School of Music's Rochester Philharmonic Orchestra. He married Bette Anne Loder on April 23, 1960 and became the youngest member of the famous Pittsburgh Symphony Orchestra in October of the same year. After two years he began performing with jazz groups including the Kai Winding Septet, Jon Eardley Quintet, Gerry Mulligan Big Band, Bill Russo Big Band, the Sal Salvador Big Band as well as the Radio City Music Hall orchestra from 1964 to 1971.

Born in Pittsburgh, PA, William Motzing attended the Eastman School of Music in Rochester, New York, alongside Ron Carter and Chuck Mangione who would also become notable musicians. He gained his bachelor's degree at Eastman in 1959, and in 1960 a master's degree from the Manhattan School of Music in New York City.
