                                An interview with Wynton Marsalis, a noted jazz musician
1_____
     There were the older jazz musicians who hung around our house when I was young. I saw how much
they practiced, how serious they were about their art. I knew then I had to work just as hard if I wanted
to succeed. Of course, my father inspired me a lot, and many teachers took the time to nurture my talent
and the talents of other students in our school.
2_____
     Yes. We've done such a poor job with music education because, as a society, we haven't maintained the
kind of education that a true artist and musician needs. Young people haven't been able to equate romance
and talent with music. For instance, most of the people who make it in the music industry today have to
look good. How they sound is secondary. Sarah Vaughan, Bessie Smith, Ella Fitzgerald-those big, romantic
queens of jazz music wouldn't make it in today's music industry, and that's a shame. We need to teach young
people about the alternatives.
3_____
     Around the world people make music that, if you listen carefully to it, sounds a little like the cadence of
their language. I'd call it folk music. When I'm away from home, I make a point of listening to regional folk
music, not what' on the radio.
4_____
     The same music is on the radio all over the world, and the American sound is overwhelming. Even the
pop music that's produced and created in foreign countries has that American beat, that underscore of funk.
As a musician, I'm not interested in hearing recycled versions of the same genre over and over. Any music
that doesn't have a development section just isn't interesting to me.
5_____
     The music press has so much to introduce these days, and jazz is just a small fraction of it. Because some
people are intimidated by jazz, they don't cover it unless it's a big name. New jazz musicians don't get much
of break. A lot of editors don't say anything about jazz these days unless it's Marsalis. That's a shame. What
VH1 is doing with their Save the Music campaign is phenomenal. They're getting all these instruments out
to needy kids. It's the kind of thing all networks should be doing.
