ladies and gentlemen, let us introduce
the teenage engineering choir.
what you see are eight wooden dolls, made to serenade you with
a repertoire of choral classics as well as perform your own original compositions through midi over ble. each member has their own characteristic vocal range. individually one can sing a dynamic solo, together they perform an immersive a cappella concert. the choir is inspired by the original absolut choir, our very first project.

the pre-programmed repertoire of classic songs have been created 
and performed using an algorithm based on counterpoint melody, 
a compositional technique that refers to the independent but complementary relationship between two or more lines of 
melody played at the same time. (applause)
tap, tilt or smack.
to get the choir started, they need a helping hand. a sensor inside the speaker module reacts to vibration and movement, so controlling choir is a playful experience in itself. gently tap the doll on its head or on the table to trigger play or pause, or tilt the doll left or right to decrease or increase the volume accordingly. if it gets annoying, it can handle a little smack to turn it off.

let us present the ensemble.
based on cultures and characters from across the world, every doll is unique and has it's own vocal tonality. while each is given their own voice type, a single doll can customize their vocal range to sing a dynamic 
solo performance. when more than one member of the choir are placed together, in any combination, they communicate with each other, 
and recognize the choral members in range, joining in 
a full choral experience.
