Duo-Art

[1] Between 1913 and 1925 a number of distinguished classical and popular pianists, such as Ignace Paderewski, Josef Hofmann, Percy Grainger, Teresa Carreño, Aurelio Giorni, Robert Armbruster and Vladimir Horowitz, recorded for Duo-Art, and their rolls are a legacy of 19th-century and early 20th-century aesthetic and musical practice.

The recording process – using a piano wired to a perforating machine – was unable to capture the pianist's dynamics automatically.

Thus, post-recording editing was required to produce the finished performance – usually a joint effort by the recording technician and the actual pianist, who approved the final product.

It was most commonly installed in piano brands manufactured by Aeolian such as Weber, Steck, Wheelock, and Stroud.

In 1925, its peak year, Aeolian produced more than 190,000 instruments, but the crash, the electric phonograph and the "talkies" all combined to drive the business into a terminal decline.
