The piffero (Italian: ['piffero]) or piffaro is a double reed musical instrument with a conical bore, of the oboe family (Sachs-Hornbostel category 422.112). It is used to play music in the tradition of the quattro province, an area of mountains and valleys in the north-west Italian Apennines which includes parts of the four provinces of Alessandria, Genoa, Piacenza and Pavia. It is also played throughout Southern Italy with different fingering styles dictated by local tradition.
The piffero has eight tone holes, one of which, on the back of the instrument, is usually covered by the left hand thumb, and ends with a bell, where a cock tail feather (used to clean the reed) typically rests during execution.
Traditionally in Northern Italy it was accompanied by an Appennine bagpipe known as the müsa. In the early 20th century the müsa was largely displaced by the accordion, which musicians found in some ways more versatile. However towards the end of the twentieth century the bagpipes made a comeback and today the piffero is commonly accompanied by either of these instruments, or by both.
Other regional names for the piffero in Southern Italy are "ciaramella" or "pipita." It is still commonly played in accompaniment with the Southern Italian Zampogna, an instrument which itself is essentially a series of pifferos stuck into a common stock and supplied with air through the use of a goat skin bag.
Piffero is sometimes used as the name of an organ stop which emulates the sound of members of the shawm family; while Piffaro (or: Fiffaro) is the name of an organ stop, also known as Voce Umana, whose sound resembles a vibrato transverse flute.
