The songwriter died after a lengthy battle with throat cancer yesterday afternoon.
Ashford was part of a songwriting duo with his wife Valerie Simpson. Together, they wrote hits including Diana Ross's 'Reach Out And Touch', Aretha Franklin's 'Ain't No Mountain High Enough' and Chaka Khan's 'I'm Every Woman'.
The pair also had their own music careers, releasing a number of albums throughout the 1970s and 1980s.
Ashford and Simpson were inducted into the Songwriters Hall Of Fame back in 2002, 36 years after their breakthrough hit, Ray Charles's 'Let's Go Get Stoned', in 1966.
Alicia Keys paid tribute to Ashford on Twitter, saying: "I'm so sad that he's gone. What a legacy of infectious music."
Verdine White of Earth, Wind and Fire added: "His music is unmatched in terms of great songwriting. They had magic and that's what creates those wonderful hits, that magic. Without those songs, those artists wouldn't have been able to go to the next level."
