Stephen B. Givens, 34, of Smyrna allegedly sent multiple texts and asked for photos from a student, investigators said.
"We received information that he was texting a 16-year-old student at the school," Detective Charles Kimbril of the Bedford County Sheriff's Department said. "We started an investigation and developed probable cause to believe it had occurred."
The student is in one of Givens' classes, investigators said.
"There were some photos sent, and he had requested photos from her. Texts were sent from her phone," Kimbril said. "I obtained a search warrant for her cell phone and also a warrant was served on him at the school."
The investigation is continuing, Kimbril said.
Givens was taken to Bedford County Jail. Bond was set at $5,000. Court date is set for Aug. 29.
He has been at Community since September 2003, according to his Facebook profile. A 1996 graduate of La Vergne High School, he holds a bachelor's degree in music education from Middle Tennessee State University and a master's degree in music conducting from Columbus State University.
