Wright met Pink Floyd members Roger Waters and Nick Mason in college and joined their early band, Sigma 6. Along with the late Syd Barrett, the four formed Pink Floyd in 1965.
The group's jazz-infused rock and drug-laced multimedia ''happenings'' made them darlings of the London psychedelic scene, and their 1967 album, ''The Piper at the Gates of Dawn,'' was a hit.
In the early days of Pink Floyd, Wright, along with Barrett, was seen as the group's dominant musical force. The London-born musician and son of a biochemist wrote songs and played the keyboard.
''Rick's keyboards were an integral part of the Pink Floyd sound,'' said Joe Boyd, a prominent record producer who worked with Pink Floyd early in its career.
The band released a series of commercially and critically successful albums including 1973's ''The Dark Side of the Moon,'' which has sold more than 40 million copies. Wright wrote ''The Great Gig in the Sky'' and ''Us and Them'' for that album, and worked on the group's epic compositions such as ''Atom Heart Mother,'' ''Echoes'' and ''Shine on You Crazy Diamond.''
But tensions grew among Waters, Wright and fellow band member David Gilmour. The tensions came to a head during the making of ''The Wall'' when Waters insisted Wright be fired. As a result, Wright was relegated to the status of session musician on the tour of ''The Wall,'' and did not perform on Pink Floyd's 1983 album, ''The Final Cut.''
Wright formed a new band Zee with Dave Harris from the band Fashion, and released one album, ''Identity,'' with Atlantic Records.
Waters left Pink Floyd in 1985 and Wright began recording with Mason and Gilmour again, releasing the albums ''The Division Bell'' and ''A Momentary Lapse of Reason'' as Pink Floyd. Wright also released the solo albums ''Wet Dream'' (1978) and ''Broken China'' (1996).
In July 2005, Wright, Waters, Mason and Gilmour reunited to perform at the ''Live 8'' charity concert in London -- the first time in 25 years they had been onstage together.
Wright also worked on Gilmour's solo projects, most recently playing on the 2006 album ''On an Island'' and the accompanying world tour.
Gilmour paid tribute to Wright on Monday, saying his input was often forgotten.
''He was gentle, unassuming and private but his soulful voice and playing were vital, magical components of our most recognized Pink Floyd sound,'' he said. ''I have never played with anyone quite like him.''
