Morricone, who scored more than 500 films, is widely regarded as one of cinema's greatest composers and won a long-overdue Oscar for his work on Quentin Tarantino's The Hateful Eight in 2015.
He also received nominations for Terrence Malick's Days of Heaven (1978), Roland Joffe's The Mission (1986), Brian De Palma's The Untouchables (1987), Barry Levinson's Bugsy (1991) and Giuseppe Tornatore's Malena (2000).
Affectionally known as `The Maestro,` Morricone was handed an honorary Oscar by Clint Eastwood in 2007, with the Academy hailing his `magnificent and multifaceted contributions to the art of film music`.
His influence also extended far beyond cinema, with Muse previously hailing Morricone as one of their biggest influences. Since 2008, all performances of the band's track 'Knights of Cydonia' have begun with bassist Chris Wolstenholme playing a harmonica solo of 'Man With a Harmonica' from Once Upon a Time in the West.
Similarly, Metallica have used 'The Ecstasy of Gold' as their introductory music since 1984 and recorded an instrumental metal cover for a 2007 tribute album to Morricone.
Paying tribute, director Edgar Wright wrote: `Where to even begin with iconic composer Ennio Morricone? He could make an average movie into a must see, a good movie into art, and a great movie into legend. He hasn't been off my stereo my entire life. What a legacy of work he leaves behind. RIP.`
