Square Piano/Pipe Organ by Longman & Broderip

This organized piano, or square piano with an organ, is an extremely rare instrument. It is signed by Eaton Pe[ther]? and the nameboard lists the piano making firm of Longman & Broderip. The case is of mahogany, with the piano on top. A hinge on the back of the piano case allows the piano to open up for access to the box below containing the organ mechanism. The bellows are located in the lower right of the case and can either be pumped by the player using a pedal to the right side of the keyboard, or by a second person standing to the side of the case.

Two similar piano-organ instruments exist, one also by Longman & Broderip (serial number 1742) in the Vienna Kunsthistorisches Museum and one by Johannes Pohlman located in the Leipzig collection. Credit: Met Museum
