Bohassa polyphonique and not Ceccola polifonica

Parla mi mazurka composed by Bernard Connac played with the bohassa polyphonique invented et created by Robert Matta in 2002. This instrument created by Robert Matta in his workshop is called by other people " Ceccola polifonica". Issued from my work on the boha " bagpipe from the Landes" it&a pure invention and had a lot of success. Some people took some profit from it and don&even mention my name. This video is just here to tell the truth.
