The dance organ came into its own during the early 1900s, with many large instruments built by Gavioli and Marenghi. In the early 1910s the firm of Mortier began expanding out the sound-schemes of these instruments with a variety of novel and new pipework and percussion adapted to the new emerging styles of early 20th century popular music. Other manufacturers such as Hooghuys and Fasano followed suit. Many instruments with older style sound schemes from Gavioli and Marenghi were modernized by Mortier and others either partially or entirely.
