i(ce)-Tunes: Sweden's incredible ice orchestra

They're so fragile even the players' breath risks nudging them out of tune. Turn up the temperature in the concert hall and you'd have, not a finely chiseled viola, flute or conga, but a glass of water. "And you'd be healthier for drinking it!" says Tim Linhart, ice-instrument maker extraordinaire to an orchestra playing a series of concerts throughout the winter in the remote Swedish town of Luleå, just beneath the Arctic Circle. Hearing is believing Hearing really is believing when it comes to these evanescent instruments made -- bar the strings and other odd parts of metal or wood -- entirely from frozen water. Linhart has held ice concerts not only in Sweden over the past 15 years but also in far-flung locations from Beaver Creek, Colorado, to the Italian alps. His main problem, he says, in attracting a greater audience to the genre is people's incredulity that an ice instrument could make more than the most rudimentary sound. A recording of an ice violinist busking a solo classical piece outside Luleå's House of Culture in around -10 C is evidence to the contrary. The sound is sharp and ethereal, with a wide tonal range. Not only classical But the ice repertoire doesn't include only refined, classical pieces. Along with the violins and a viola, cellos and a bass, there's an ice banjo in this year's lineup to accent country and bluegrass numbers. Six- and 12-string guitars suit rock 'n' roll, and an ice xylophone resting on bicycle inner tubes -- to aid its resonance -- works across the genres. As for the orchestra's gigantic spherical "bubble drums," Linhart tells CNN, "they really shake your skeleton." Doubtless they'll be deployed to funky effect in the -- inevitably, this being Sweden -- series of Abba-themed concerts among the 40 or so on the program this year. Winter pursuit A stone sculptor in warmer months, the bearded Linhart, 53, makes all the instruments for the winter concerts in a six-week burst in his back garden. They're transported to a specially built igloo auditorium seating 170 people in a nature park outside Luleå, where the orchestra plays. Originally from New Mexico, Linhart was invited to this town of 80,000 residents in Swedish Lapland 10 years ago to take part in the building of one of the world's first ice hotels.

Lovers of a cold climate So, apart from loving a sub-zero climate, how else do ice instruments differ from the conventional kind? They're quicker to make, for a start, Linhart says. "I can do the carving on the front and back plate of a standup bass in two hours. "The chisel just glides through the ice. "My tools are similar to those of a regular instrument maker," he says. But when it comes to sealing one of his creations together, "the only glue I use is water." "If you want to glue a crack in an ice instrument, you just take a little straw, blow through it until the ice melts and then let it freeze again. "With wood, you can only carve. "With ice, you can also grow." Just add water! Another difference from conventional instrument making? Linhart wears dishwashing gloves while he's carving, something you wouldn't see many master violin makers doing.
