People in about 40 countries are expected to view Saturday's high-definition "Live from Orchestra Hall" webcast.
The DSO says it's the only U.S. orchestra to offer a free series of webcasts.
The Symphony says the webcast player "mimics the actual interior" of Orchestra Hall. Dimming controls allow the virtual viewer to adjust lighting.
Saturday's webcast will feature a performance of Mozart's Horn Concerto No. 4. The orchestra says it expects its webcast series to surpass 30,000 views with this weekend's episode.
The piece will be highlighted on a live repertoire tracker, and live program notes will post below the viewing window with trivia about the piece and the artists.
