this is quite an interesting surprise to find out about this instrument.
I remember when i saw amusical group from Asturria, which is probaly
Basque territory?? called Llan de Cubel, they had another unique instrument-it was like a giant key board that the mandola player
played with his feet..looked like those pedals at the bottom of
an electric organ, only they were huge and he tapped them to play
a bass line while playing his stringed instrument as well. It sat
on the floor in fromt of him. I had to sneak to a forbidden place
in the balcony to be able to see to find out what he was doing with his feet!
