"The Pointer Sisters would never have happened had it not been for Bonnie."
The Pointer Sisters - at different times including Bonnie, Anita and their siblings June and Ruth - formed in Oakland, California, and first found success in the 1970s.
Their best-known songs include Jump (For My Love) and I'm So Excited.
The group won three Grammy awards and were honoured with a star on the Hollywood Walk of Fame in 1994.
Bonnie left the group in 1977 and pursued a solo career.
Bonnie is survived by her brothers Aaron and Fritz, as well as sisters Ruth and Anita Pointer, a representative said.
