Dissolution of the salt stone

The piece was inspired on a comentary about  electroacoustic music made by a musical journalist;  he used the term salpetrous to describe it . Following this  idea I thougth that   instrumental music would be related to a liquid image. Also, that it would be interesting to compose a piece in which salpetrous structures  would evolve until dissolve. Two times four chords  are   the initial material of the composition. I ve transposed the notion of filtering, or sustratcive synthesis  to instrumental writing, applying it  to  the evolution of harmony  and  rhythm. The salt stone has also a symbolic dimension in jewish tradition, and the notion of  a gradual dissolution of a form it s one of my strongest compositional obsessions.
