That is a special Tabor-pipe from Katalonien/ Espagna.
It has not 3 holes but 7 holes.
The left hand plays with three fingers the holes on the front and with thumb and the small finger two holes on the backside. .
The right hand plays the three holes downstairs for the deep notes.
So you can play two full octaves at this flute.
Actual we have the flabiol made from black plastic, not like the pictures.
