Portative organ
A portative organ (portatif organ, portativ organ, or simply portative, portatif, or portativ) (from the Latin verb ''portare'', "to carry"), also known as the ''organetto'', is a small pipe organ that consists of one rank of flue pipes, sometimes arranged in two rows, to be played while strapped to the performer at a right angle. The performer manipulates the bellows with one hand and fingers the keys with the other. The portative organ lacks a reservoir to retain a supply of wind, thus it will only produce sound while the bellows are being operated. The instrument was commonly used in secular music from the twelfth to the sixteenth centuries.〔"Portative organ." ''Encyclopaedia Britannica'' (2007).

==Construction==
The portative is constructed simply in order to make it as portable as possible. The pipes are arranged on a small rectangular windchest and supplied with wind by one or two bellows placed at the back, in front or at the right side of the instrument. The row of pipes is supported by posts at either end and an oblique bar. The simplest style of keyboard on the portative consists of one slider for each pipe. When a slider is pushed in, the corresponding pipe sounds. The slider is restored to its normal position by a horn spring. Some instruments use the reverse of this action, with keys featuring knobs or handles.
