Carlo Annibale Tononi was a luthier who trained and worked with his father in the Tononi family workshop in Bologna, Italy. Before his death, Tononi modified his will to provide for his funeral. He requested that the proceeds from the sale of one of his cellos be used to pay for a mass to be said for his soul. On 21 April 1730, his executors published his will after his death. A genuine Tononi violin ranges in value from $45,000 to $450,000 depending on condition and provenance.
