Foundation “Deca deci” is a non-profit organization, founded in 2007 in cooperation with the Belgrade Philharmonic, under the auspices of the City Assembly of Belgrade. By getting involved in music programs crafted according to the highest professional standards, with children as performers, in collaboration with experts from different fields, children acquire knowledge and learn stage performance skills, which contribute to their professional development and education. Apart from the children orchestra and soloists who audition every year, the Regional children's philharmonic was formed of children musicians from five cities from the region: Ljubljana, Zagreb, Sarajevo, Skoplje, and Belgrade.
