The curator of contemporary music and arts festival MONA FOMA says it is becoming a destination for tourists from all over the world.

More than half the tickets sales for the annual festival in Hobart have been from outside Tasmania.

Curator Brian Ritchie says the festival, which runs till Sunday, has fast become a cultural drawcard for the state.

"Its becoming a destination, MONA FOMA and its an intellectual and spiritual and artistic destination I suppose."

Mr Ritchie says Tasmanians are also embracing the festival.

"The things that make MONA FOMA special is its the experimental side of the music and the art would be meaningless but for the fact the public comes along in huge numbers," he said.

"They really give it a go and we're getting to the point now where people say I didn't know what to expect but that was great, or I didn't like everything but I'm glad you're doing it."

This year's festival features theatre performances, art and sound installations and an eclectic mix of music, including Ethiopian funk, Indian bongos and lullabies on violin.

A new attraction is the giant Theremin, a seven-metre high electronic instrument that produces sound simply by people walking past or dancing around it.

Among the more unusual performances has been from "extreme drummer" Tina Havelock Stevens.

She will be craned into the Derwent River in a cage and will playing drums "underwater style."

Organisers are hoping to top last year's crowd of 30,000 people.

They are also keen to see the festival grow each year.

"I think cultural tourism and arts tourism is obviously on its way up in Tasmania and that's pointing at least one direction for the future and people have adopted this kind of creative mentality as part of the Tasmanian identity,'' Mr Ritchie said.

The MONA FOMA program runs until Sunday but there will also be a special bushfire appeal concert on Monday night.
