It's not only Little Mermaid and her friends who can sing and perform music underwater. A controversial new band called "AquaSonic," is making headlines in water and on land by being the first band to ever perform underwater.

At first glance, the band AquaSonic is like a contestant in a talent show like "America's Got Talent," a show that showcase unique performances. One may find their music haunted, but it is truly melodic in a weird kind of way.

The band is first artist to perform in giant aquariums, On May 9, New Scientist posted a video of their performance on Youtube. According to reports, the secret of the two vocalists is that they can sing underwater by refraining from blowing bubbles.

During the concert, there were five giant aquariums on a stage. Each musician in the band is submerged in each tank, and played an instrument or/and sang underwater.

Obviously, singing or even making a vocal sound underwater is difficult. Some instruments can not produce sound underwater. So AquaSonic made an experiment. After 10 years of experimenting, the singer and composer Laila Skovmand and the rest of the band have found a way to make music underwater.

"It's wild, it's been a long trip," Skovmand said. "I will be lying at the bottom of a tank and singing, using a technique I came up with myself," she added.

During the band's experiment with aquatic singing, Skovmand submerged her mouth in a kitchen bowl filled with water and tried to produce a steady vibrato. When they had a diving trip, she tried singing underwater. It worked. However, there were lots of bubbles produced, thus adding popping sounds to the vocals.

Skovmand found a way to prevent producing bubbles when she sings. Her technique is to keep an air bubble in her mouth and sings through it when submerged. To avoid losing oxygen in her body, she must rise to the top every minute to take in a breath and a new bubble.

"There is also a technique where I switch between singing on the exhale and inhale," she says.

"But it can be hard to control," added the uncommon singer.

Due to the small amount of air in a bubble, the singer can only produce short tones. High notes also tend to sound better than lower notes, which sound nasal.

In 2012, the group posted a video of their work-in-progress concert in Denmark.
