Jan Novak's (1921 - 1984) Iubilationes (Nova Rise (New Empire) 1921 - Neu Ulm 1984) are one of these works, which can be described as being typical organ music. Both sections basically make use of two organ sound positions. The Iubilatio matutina is based on the lustre of the organ's stops and in its concept resembles the style of High Baroque preludes and fugues. Its festive tones evoke an atmosphere of joy. On the other hand, the Iubilatio nocturna has a chamber music-like tone and makes use of the great sound diversity of the instruments. In its character it calls to mind the contemplation of a lonely man in the silence of the night. However the composer merges this character contrast in both sections into one precise thematic work and internal links, which makes this cycle a brilliant composition filled with rising invention and great feeling for all the specific qualities of this regal instrument.<br>
