The Girls’ Choir of the Koper Music School evolved from the Koper Music School Youth Choir. The choir has been singing for nine years under the leadership of Maja Cilenšek and regularly scores at the top of international competitions. In July of 2015, the choir participated in the “Incanto Mediterraneo” international competition in Milazzo, where they won the gold medal, placed second, and received special commendation for best performance of the mandatory composition. In September of 2017, they were awarded 95 points at the “International Baltic Sea Choir Competition” winning second place; they also received the award for best performance of the mandatory composition Lux Aeterna by Ēriks Ešenvalds.

Maja Cilenšek includes new compositions by Slovenian composers in her repertoires and so stimulates the creation of new works for youth choirs. As lecturer and expert panellist she is regularly invited to attend various seminars and singing events. At the 2007 “Mariele Ventre” competition in Bologna she shared first place with Italian conductor Lorenzo Donati.
