The "Gaudeamus" chamber orchestra was founded in 2002 as a part of ŠKUC (Students' cultural centre). It consists of students of Ljubljana Academy of Music, postgraduate students of foreign academies and young musicians, all of them winners of numerous national and international awards. The orchestra consists of: 9 violins, 3 violas, 2 violoncellos, contrabass, flute, oboe, clarinet, bassoon, horn, trumpet, trombone, piano (harpsichord) and percussion. A string quartet and 14- member ensemble for modern music also form a part of the orchestra, the basic function of which is presentation and affirmation of young authors and interprets, for the orchestra's focus lies in performing modern, and above all, Slovenian music. Despite its rather short existence, "Gaudeamus" can pride itself on more than twenty first performances of works by young Slovenian composers and cooperation with numerous young soloists. Both the orchestra and the ensemble are led by conductor Aleksandar Spasić.
