Carving each instrument can take up to 12 hours, says Bill Covitz. He’s an ice carver from Connecticut who helps with the festival almost every year. To hollow out a horn, Covitz slices a piece of ice down the middle. Then he carves a groove in each half. Smaller tools, such as chisels, help him carve finer details. Finally, he puts the halves back together and sprays them with water. This freezes them in place.
An ice music concert is a cool experience—literally. The musicians perform at night, when temperatures can drop to -15°F. Performers wear thick gloves and use leather lip guards to protect their skin while they play their icy instruments. “In the cold, the instruments sing beautifully,” says Covitz.
If an ice instrument gets too warm, it starts to melt. That changes the instrument’s shape and makes the sound duller. This can happen during performances, like when a musician’s warm breath heats up a horn. But Isungset thinks that keeps ice music interesting. “My favorite thing is when the audience gets surprised,” he says.
