US trumpet star Roy Hargrove has opened the Edinburgh Jazz and Blues Festival with a performance at the Queen's Hall.
The programme for the 31st festival also includes top names such as Courtney Pine, Jack Bruce, Martin Taylor and Jools Holland.
A jazz orchestra directed by veteran Scots saxophonist Joe Temperley, 79, will be another of the highlights.
There have also been free events such as the Mardi Gras and Jazz on a Summer's Day in Princes Street Gardens.
The 10-day festival uses 19 venues, ranging from formal concert halls and clubs to unusual settings such as The Signet Library and Rosslyn Chapel.
Pianist Dick Hyman will play a concert of jazz on the harpsichord in the Georgian splendour of The Signet Library.
Baptiste Trotignon performs solo in the magical atmosphere of Rosslyn Chapel.
The festival's line-up of blues artists includes Scots exiles Jack Bruce, the former guitarist of rock band Cream, and Maggie Bell.
It also features Eric Burdon, Lisa Mills, Lightnin' Willie and Otis Grand.
On Saturday, the festival's famous Mardi Gras, which offers prizes for audience members wearing the best carnival mask or costume, was headlined by Tam White.
The programme also includes 79-year-old Scottish jazzman Joe Temperley directing the Edinburgh Jazz Festival Orchestra in a tribute to Duke Ellington.
Temperley, from Lochgelly in Fife, played as a member of Duke Ellington's Orchestra and for the past 20 years has been with what is widely regarded as the world's leading Big Band, The Lincoln Center Jazz Orchestra, under the direction of Wynton Marsalis.
Brian Fallon, chairman of the Jazz Festival board, said: "We're delighted to continue to expand the festival and to bring so many high quality artists to Edinburgh to delight and thrill both local audiences and visitors."
Culture Minister Mike Russell said: "Scottish jazz musicians are playing some great music right now and The Scottish Jazz Expo raises the profile of our jazz and blues music throughout the world."
