Cleveland Orchestra music director Franz Welser-Möst opens the orchestra’s family season with an introduction to his ensemble today. He’ll lead them through music selections that showcase each section so kids can get a feel for the sounds of the different string, woodwind, brass and percussion instruments. You can show up an hour before the concert for free interactive activities, including an up-close introduction to the instruments. It starts at 2 p.m. at Severance Hall (11001 Euclid Ave, 216.231.1111). Tickets: $10-$23. — Michael Gill
