The programme of Slovene Music Days, existing since 1985, is divided into two main parts: an international musicological symposium and concerts of contemporary Slovene music. Each year the international musicological symposium led by Jernej Weiss (1985-2015 by Primož Kuret) brings together about 30 musicologists from all over Europe to discuss a different topic. Part of the symposium has been dedicated to examining and studying the works and lives of Slovene composers. The concert part begins and ends with two Slovene orchestras, the RTV Slovenia Symphony Orchestra and the Slovene Philharmonic Orchestra. In 2021 the festival takes place online.
The programme contains a number of accompanying events, such as round table discussions, music workshops, exhibitions, and book presentations. It is usually held at the halls of the Slovene Philharmonic and at the Knight’s Hall at Križanke. Previously it was also held elsewhere, as for example in the Piran City Gallery in Piran-Pirano.
Among many renowned musicians who appeared at the festival in recent years, the Slovene Music Days has also hosted the Slavko Osterc Trio, SToP Slovene Percussion Project, RTV Slovenia Big Band, the Academic Choir Tone Tomšič, Carmina Slovenica and the Ensemble Modern.
