 Volume IV contains two works which belong to the group of larger-scale compositions completed by the composer himself. The Contrapuntal Symphony was the last work to be published during the composer’s lifetime. The manuscript of the Chaconne was considered to be lost until recently and it is now being published here for the first time.<br>
