This third publication of quartets presents another 4 compositions ( in the overall sequence 9-12 ) for four percussion players. These quartets are designed to teach the use of chamber music presentations at school or other appearances. These  compositions are not seeking to experiment with new sounds, offer exotic new instruments or impress by unreadable notation. The aim is to create a readable and understandable music with a common armamentarium of percussion, that should draw the attention to their possible rhythmic-melodic independence.
