During climbout the Captain noticed a vibration in the control column when banking left. This vibration was also accompanied by a low tone; but loud vibration type noise that was noticed by the Captain and I as well as the Flight Attendant and passengers. Due to the concern with a flight control issue/vibration we contacted Dispatch to let them know of the issue and that we wanted to return back to the airport. The Dispatcher acknowledged our ACARS and we returned back to the departure airport.Possible flight control issue; communication between pilots as well as Flight Attendant; obtaining new clearance and workload management to get the aircraft; passengers and airport operations aware of our air return.The air return was well handled as the Captain took over flying and some radio duties while I communicated with Dispatch; Maintenance and airport Operations. The proper workload management that occurred on the flight deck aided open communication between both pilots as well as the Flight Attendant which also led to there not being a rushed sense in the cockpit but still had a sense of urgency. Keeping it slow; keeping lines of communication and simplified aided in a smooth precise air return. Overall threat and error management techniques learned through recurrent training played a huge role in aiding with a smooth safe air return.
