Organetto refers to two distinct instruments: the medieval organetto, or portative; and the modern organetto.
The medieval organetto  was a portable, hand-pumped pipe instrument, allied to the later classical pipe organ. It is referenced in the Roman de la Rose: "There are easily manageable organs which are portable and are pumped and played by the same person, who also sings either the soprano or tenor part." It was among the most popular instruments in Europe from the 13th to the 16th century. It was relatively lightweight, and could be carried with a sling for use in religious processions and other occasions. Bellows provided the wind supply, and a button-type keyboard could be used across approximately two octaves. It could play only one note at a time, and was used for a single part in a polyphonic piece, motet or chanson, and for monophonic dance music.
