The festival is being arranged under the auspices of the Ministry of Culture of the Republic of Macedonia. The festival is also supported by municipality of Bitola and was occasionally supported by Ministries of Education, Defense and Internal Affairs run by Polozani, Tomislav Cokrevski and Blagoj Handziski.
From 2000 to 2005, the general sponsor of the festival was Kometal trade with Trifun Kostovski who, in 2002, donated to the city of Bitola, the concert piano “Boesendorfer Grand Concert 280”
The festival is ranked as an event of national significance.
The program is distributed on eleven festival evenings and is consisted of 13 -15 concerts and musical stage performances (opera, ballet), 2 – 3 theater plays and one night of poetry, where eminent Macedonian poets are presented. The participating ensembles range from solo performers, through chamber orchestras, to symphonic orchestras and choirs. National Theater Bitola is participating every year with premiere play. A significant number of concerts and balet plays were broadcasted live or recorded by the Macedonian Radio and Television.
Some subsidiary activities at the festival include Master Musical Schools, painting and archeological exhibitions. The Master classes, which are run by remarkable artists – professors of the most distinguished world conservatories, instruct in various practices, such as piano, violin, violoncello, solo singing, trombone, trumpet, clarinet, guitar, etc. In the recent years the Master classes were of a regional character and besides the pupils, students and young artists from Macedonia, candidates from other Eastern European countries also took part.
In the last 18 productions of the festival, over 300 festival events have been performed, presenting artists from some fifty countries from Europe, Asia, North and South America, Africa and Australia, many of which are from the leading world music scene. The festival is held in the facilities of the Institute, Museum and Gallery, National Theatre, the Cultural Center and churches of St. Dimitrija, St. Bogorodica (spiritual music). Some of the concerts are dislocated at Skopje, Prilep, Kumanovo, Shtip, Strumica.
