Some of the world's most famous musicians recently gathered in Paris and New Orleans to celebrate the first annual International Jazz Day. UNESCO( United Nations Educational, Scientific and Cultural Organization) recently set April 30 as a day to raise awareness of jazz music, its significance, and its potential as a unifying(联合) voice across cultures.
Despite the celebrations, though, in the U.S. the jazz audience continues to shrink and grow older, and the music has failed to connect with younger generations.
It's Jason Moran's job to help change that. As the Kennedy Center's artistic adviser for jazz, Moran hopes to widen the audience for jazz, make the music more accessible, and preserve its history and culture.
“Jazz seems like it's not really a part of the American appetite,” Moran tells National Public Radio's reporter Neal Conan. “What I'm hoping to accomplish is that my generation and younger start to reconsider and understand that jazz is not black and white anymore. It's actually color, and it's actually digital.”
Moran says one of the problems with jazz today is that the entertainment aspect of the music has been lost. “The music can't be presented today the way it was in 1908 or 1958. It has to continue to move, because the way the world works is not the same,” says Moran.
Last year, Moran worked on a project that arranged Fats Waller's music for a dance party, “Just to kind of put it back in the mind that Waller is dance music as much as it is concert music,” says Moran. “For me, it's the recontextualization. In music, where does the emotion(情感) lie? Are we, as humans,gaining any insight(感悟) on how to talk about ourselves and how something as abstract as a Charlie Parker record gets us into a dialogue about our emotions and our thoughts? Sometimes we lose sight that the music has a wider context,” says Moran, “So I want to continue those dialogue. Those are the things I want to foster.”
