But it's Jones' unique and seemingly endless compositions that have made his music a natural choice for Smithsonian's jazz orchestra.
"Quincy's composing and arranging was, and still is, a singular voice," says Smithsonian jazz expert John Edward Hasse. "His music doesn't sound like anybody else's and it has a secure place in history."
Last winter, the Smithsonian orchestra developed a program, The Big Band Works of Quincy Jones, which it performed in Toronto, Washington, D.C., Virginia and Indiana. Baker says Jones has gone out of his way to help the orchestra. The group often has trouble getting the rights to play music, but Jones "has been so big hearted. Every time we called on him the music was made available to us."
Baker remembers visiting Jones in preparation for the recent tour. He says Jones went into his vast music vault and sorted through dozens of different arrangements of a particular song to find the right one for the orchestra.
Jones got to hear the orchestra play his tunes last January in Toronto, when he was recognized as a Jazz Master by the National Endowment for the Arts. He "was knocked out," Baker says. "It was so much fun to watch him in the front row digging on that stuff."
Hasse, a curator at the Smithsonian's National Museum of American History, has also worked closely with Jones, who wrote the foreword of Hasse's book Jazz: The First Century.
Hasse first met Jones in the early 1990s while working on a video about Duke Ellington. In July 2001, Hasse took Jones on a tour of the museum's jazz collection, showing him Dizzy Gillespie's trumpet, 100,000 pages of unpublished music by Duke Ellington and even a letter Jones wrote to Ellington.
And that month Jones also conducted several of his songs with the Smithsonian Jazz Masterworks Orchestra.
"It was marvelous," says Hasse. "He poured himself into the conducting with such intense passion that he actually got so excited that he jumped up into the air about a foot, twice, and at that point he was no spring chicken."
As Baker says of Jones, "He seems indefatigable."
