The music world has been rocked by the loss of the singer/ songwriter - who sold over 220 million records and changed the face of disco music alongside his brothers Barry and Maurice in the group - and many have rushed to offer their condolence and pay tribute.
Broadcaster Paul Gambaccini described Robin as ''one of the major figures in the history of British music''.
He added: ''What must also be said is Robin had one of the best white soul voices ever. He was singing lead on his first number one when he was 17.
''Not only have they written their own number one hits, but they wrote huge hit records for Barbra Streisand, Diana Ross, Dionne Warwick, Celine Dion, Destiny's Child, Dolly Parton and Kenny Rogers, the list goes on and on.''
The Bee Gees were famed for their tight vocal harmonies on hits such as 'Stayin' Alive', 'Massachusetts', 'I've Gotta Get a Message to You', 'How Deep Is Your Love' and 'You Win Again', and helped Usher in a new era of pop in the disco era of the 70s.
'Run to You' rocker Bryan Adams paid tribute, saying: ''Robin Gibb RIP. Very sad to hear about yet another great singer dying too young.''
Robin's twin brother, Maurice, died in 2003 after complications following an operation to correct an intestinal blockage, leaving Barry, 65, as the only surviving member of the group.
Singer Justin Bieber also offered his condolences, telling MTV: ''I definitely listened to the Bee Gees. I'm not too familiar with them, but it's definitely sad what happened. My heart goes out to him and his family.''
He said: ''We live in a world with changes happening more rapidly. We won't see them ever again. That's a heartbreak. The Blessing is we're able to feel the pain, which means we were able to feel some love from that person; feel the experiences the music gave us.''
Robin is survived by his wife, Dwina, daughter Melissa, 37, and sons Spencer, 39, and Robin-John, 29.
