One of those kumu hula is Ke'ano Ka'upu, who has been a top finisher in the past. He grew up in Hilo and first started participating in 1990, and over the years has gone from spectator to dancer — doing costumes, hair and singing, too, along the way. The festival is "part of that fabric that makes up the small, sleepy town," he says.

The Merrie Monarch Festival brings in competitors from around the world from different "hālaus," or schools, to dance to "meles," or songs, led by "kumu hula," or leaders.

A competition known as the "Olympics of hula" is underway in Hilo, Hawaii, this week.

"It's really hard to dance hula if you don't feel. It just makes you feel."

Now, Ka'upu is taking his own hālau, Halau Hi'iakainamakalehua, to compete, alongside fellow kumu hula Lono Padilla.

"In the whole scope of things, we're a very young hālau. We're the baby kumu hula, among some other baby kumu hulas, and then among some of the elder kumu hulas as well who have been in this competition for 30, 40 years," he says. "We're very honored, and we're very proud to be able to take this journey with them."

It's rare for a relatively new hālau like Ka'upu and Padilla's to gain entry to Merrie Monarch, he says. Some hālaus have to wait as long as 15 years for the chance.

The festival was named by the last of Hawaii's kings in the 1870s, King Kalākaua, who is credited with restoring hula's place in Hawaiian society. Hula, especially in a competitive setting, is a difficult feeling to describe, Ka'upu tells Here & Now's Jeremy Hobson.

"It's really hard to dance hula if you don't feel. It just makes you feel," he says. "For me, all senses start to work, all senses are activated. I am able to release emotions that maybe my everyday life doesn't allow me to at the moment. Once I'm dancing or I'm chanting, I'm in another world — a lot of times, I don't remember a performance, if the my wailua, my spirit, is dancing."

Hula has evolved over the years, but it's thriving, Ka'upu says, and Merry Monarch remains a benchmark for the dancing's cultural resurgence.

"[Hula] touches upon every aspect of Hawaiian culture," he says.
