More images of the girls from Move to the Music! This is Melody Atherton, she is the lead singer, songwriter and head of the band. Herself and Isabella Sanchez founded the band in the late 90's.
Since mice are only about 8"+ in height they can not play most traditional musical instruments. However with the dramatic shrinking of electronics in the 90's and the increase in easily available computing power it was just possible to explore new ways to create music. The bracelets and anklets that Melody is where are transmitters that sensors located around the girls performance stage can detect. These sensors translate movement and location into musical notes. Also the floor of the stage is rigged so if step in center places it also generates musical notes. Therefore the girls are literally able to generate music by dancing. Hence the name of the group.
Of note, the transmitters, belt antenna/ battery and microphone that Melody are of the first successful generation to work under the rigors of on the road touring since the equipment has undergone steady evolution and improvement.
