Estonian National Symphony Orchestra

Estonian National Symphony Orchestra (known as Eesti Riiklik Sümfooniaorkester or ERSO in Estonian) is the longest continually operating professional orchestra of its kind in the country. The orchestra's history dates back to 1926 and, like that of many other world orchestras, is connected to the birth of national broadcasting.

For many years, the Orchestra had word Radio in the name, but it was changed to 'State' (or 'National') in 1975.
