 As the pianola, in its turn, was supplanted by the newer Aeolian's "Duo Art" reproducing piano (1913), which could reproduce the sound of a famous artist playing without manual intervention, the Aeolian, Weber Piano & Pianola Co. became the world's leading manufacturer of such roll-operated instruments.In 1916 the Aeolian Co. started making Vocalion phonographs and in 1917/8 started Vocalion Records, a maker of high-quality discs which in December 1924 was sold to Brunswick Records.The phonograph was one of the main factors in the demise of the player piano, although Starr made players and records as well as pianos.
