FLORIDA ORCHESTRA: BEETHOVEN’S FIFTHLudwig van Beethoven’s Symphony No. 5 begins famously — da-da-da-daaaaah — and builds through mind-boggling elaborations on that motif. Music director Michael Francis conducts as the Florida Orchestra opens its season with the masterpiece more than 200 years after it was written, plus Valentina Lisitsa playing Sergei Rachmaninoff’s Piano Concerto No. 2 and Pines of Rome, Ottorino Respighi’s four-movement symphonic poem. 8 p.m. Friday at the David A. Straz Jr. Center for the Performing Arts, 1010 N MacInnes Place, Tampa; 8 p.m. Saturday at the Mahaffey Theater, 400 First St. S, St. Petersburg; and 7:30 p.m. Sunday at Ruth Eckerd Hall, 1111 N McMullen-Booth Road, Clearwater. $18-$58.

Those prices have now changed to $18 to $48, with concerts in demand (including this weekend’s concert) going as high as $58. The reason for the adjustment, the orchestra said in a statement: "A lot has changed since then...Our goal is to better blaance cost and demand while still remaining affordable for all."A CLOSER LOOK: INSIDE THE MUSICThis season the orchestra increases its special Inside the Music presentations, essentially free geek-out sessions deconstructing the weekend’s main concert piece. This time it’s Beethoven’s Symphony No. 5. The mood is casual, relaxed and fun. 7:30 p.m. today at the Palladium, 253 Fifth Ave N, St. Petersburg. Pay what you can at the door.

Abby Mann’s play fictionalizes the Judges’ Trial, one of the military tribunals after World War II."The play is about the conspiracy of silence," said Karla Hartley, Stageworks’ producing artistic director who is co-directing this show with Matthew Ray. "And if you are silent, are you any better than the people who are doing things that are objectionable or murderous? This kind of thing is cyclical, and if we don’t examine it now and again then it’s going to keep happening." Runs Friday through Oct. 14. 120 E Kennedy Blvd., Tampa. $30-$35. (813) 374-2416.
