The subject of today's Global Hit was born where the tango was born in Argentina.

Hector del Curto became a master of the banoneon. That's the button accordion that's essential to traditional Argentine tango.

Del Curto moved to New York a decade ago, when the tango dance craze was spreading across America. Now he wants people to focus less on the dance and more on the music.

Hector Del Curto says he first heard tango in the womb.

DEL CURTO: "I was born and raised and I will walk on the streets and hear tango all over the place. I don't know if it's in my blood but it's in my brain for sure."

Tango has been pulsing through the Del Curto family for more than a century. Del Curto's great grandfather played the bandoneon.

DEL CURTO: "But, since in those days being a musician was not something you would not want for your children, my grandfather was not allowed to play bandoneon, but he managed to play anyway. So he would just play for the family and friends, go on picnics, take the bandoneon, disappear for 3 days, and come back."

Del Curto took up the instrument at the age of 11 and quickly rose to the top. By age 17 he'd been invited to join the orchestra of Osvaldo Pugliese, a musician who's called the "Last Giant of Tango."

Del Curto says that around that time, he was one of only a handful of musicians in the world who really knew how to play the bandoneon. And for good reason.

The original instrument was born in Germany 150 years ago and was brought to Argentina by immigrants. Del Curto's bandoneon was made by a German factory in 1930.

DEL CURTO: "They are not made anymore, after 1939 with the war, all the materials went to the war and they couldn't reproduce this instrument."

The buttons are on either square end of the bandoneon, and the bellows stretch out to about 4 feet. It's tricky to play because the buttons are not arranged in a scale. Del Curto demonstrates by playing them in order.

DEL CURTO: "It's a little bit crazy. One note, opening would be this one; the same button when you close would be this one."

And some notes, are just missing.

DEL CURTO: "Many people now in New York are buying bandoneons to study and they go for two months and they call me back. Not to take a class but to find someone to sell it."

A worldwide tango craze began in the late 90s, when the dance show Forever Tango hit Broadway. It's what brought del Curto to the United States, and also spawned little tango communities around the US. Classical guitarist Beau Bledsoe helped get one scene started in Kansas City.

BLEDSOE: "Every little town has it now and of course that resulted in our group Tango Lorca here in Kansas City getting some work and travelling around."

Bledsoe and del Curto met at a tango festival about two years ago, and began collaborating. They're both concerned that the tango phenomena is too focused on dance, and the noisy crowds don't pay attention to the music.

DEL CURTO: "People go to dance because it's a challenge. It's something that they will do after the office and they will go to do as many steps as they can."

So just like his grandfather escaped to picnics with his bandoneon, del Curto's been coming to Kansas City as a kind of musical retreat.

Del Curto and Bledsoe have assembled a sextet of musicians from New York and Kansas City. Here they play a rarely performed piece by the legendary composer and bandoneon player Astor Piazzolla .

In a concert setting, they have the opportunity to explore Piazzolla, who strayed from traditional tango to compose in classical and jazz formats.

But Del Curto hasn't abandoned dancers entirely. Back in New York City, he teaches musicality workshops for them. And he's revived the traditional 10-piece tango orchestra to create a sound to match the energy of the dancers

DEL CURTO: "Here we go, big orchestra with a lot of bandoneons violins. Make a big sound. So they will have to listen."

This week in fact, his big orchestra, Eternal Tango, will be performing for dancers in New York outside Lincoln Center at the Midsummer Night Swing Festival.
