The treatise deals with the beginnings of symphony music performance in Ostrava from the late 19th century (until the construction of the National Centre and the German Centre). After 1900, Ostrava was regularly visited by many eminent symphonic orchestras like the Czech Philharmonic Orchestra or the Viennese Tonkünstlerorchestr, many amateur orchestral societies (such as the Orchester-Verein für classische Musik, Mährisch-Ostrauer Symphonieorchester-Verein, Orchestral Association in Vítkovice). The greatest flourishing of symphonic music in Ostrava can be attributed to the chief conductor of the Moravian-Silesian National Theatre Jaroslav Vogel. Starting at the 1927/1928 season, he introduced (and until ultimately leaving Ostrava in 1948, conducted) regular subscription concerts of the opera orchestra, which was bolstered by members of other Ostrava-based orchestral bodies (particularly from the German opera and the Radiojournal orchestra – Moravian-Silesian Radio Orchestra founded in 1929). This orchestra, led by Jaroslav Gotthard, became the basis for the Ostrava Radio Orchestra, founded in the first half of the 1950s, which in turn gave birth to today’s Janáček Philharmonic Orchestra Ostrava.
