La, la, la is the title of these three glass plates with a diapason. Bernard Moninot (Le Fay, Burgundy, 1949) seeks to communicate the imprint of sound through glass, a fragile, highly subtle material whose feature is transparency.
The artist has used the silkscreen technique: the sound generated by the diapason makes a liquid move (which could be an acid) on the glass, which is in turn engraved by the effect of the corresponding vibrations.
