A New York City taxi driver has hit all the right notes by returning an 18th-century viola worth thousands of dollars to a passenger who left it in the back seat of his car.

New Jersey Symphony violist Ann Roggen says she was heartbroken when she realized she had left her instrument in the cab.

She says she called the city's 3-1-1 help line after realizing what she'd done Thursday.

On Friday, city Taxi and Limousine Commissioner Matthew Daus appeared at her door with the $40,000 viola in hand.

The commission says cab driver Deniz Getting will receive an award for returning the instrument.
