The children's choir Iuventus, gaude! was founded in september 2005 in the Art school in Jablonec nad Nisou. The choirmaster is Bc. Anežka Šebová. During its activity the choir became an important and appreciated part of the culture life in north of the republic, almost immediately it started to achieve prizes in the Czech republic and also in other countries. More importantly it found many supporters among the spectators, the choir believes that there's nothing more worth then bringing a joy to a spectator's heart through the beauty of choir singing.

The choir is successful thanks to the diligence, excitement and talent of those children and also thanks to great job of pedagogues with support of the Art school in Jablonec nad Nisou and finally with help of parents.
