SOUTHLAKE — Above the cacophony of horns, strings and xylophones, 10-year-old Tyler Angerhauer placed his lips on the mouthpiece of the trombone and blew, letting out a distinctive bellow that could be heard above all others.His hands moved the slide on the instrument and he smiled with a big, toothy grin."I’ve never played the trombone. I’ve seen them, but I’ve never played one," Tyler said. "I felt like I was the big boss of the room."It was a night of firsts for many of the children who attended a kid-friendly concert put on by the Fort Worth Symphony Orchestra at White’s Chapel United Methodist Church.Before the show, more than 60 children crowded around tables for an "instrument petting zoo" where they played a variety of instruments.Aria Bhatki, 6, tried some wind instruments but she preferred the strings on the violin."It had cool sounds," she said."They got to hear mommy practice playing a clarinet, which I haven’t played in 20 years, maybe 25," said Aria’s mother, Leah Bhatki.Trish Rodriguez, vice president of development for the Fort Worth Symphony Orchestra, said the child-oriented concert is part of the group’s educational mission.The FWSO has performed several times in Southlake, but this was the first kid-friendly show. Entitled, "Picture the Music," the show featured more than 60 musicians playing child-friendly songs filled with imagery."We know this is really a family friendly community," Rodriguez said. "It’s really set up to keep kids interested and engaged. It’s just such a perfect match for the kids to experience the instruments and see them and hear them on-stage."
