To construct the seething movement of the piece, he iannsi the ‘molecules’ according to a coherent sequence of imaginary temperatures and pressures. This piece was made into a ballet by George BalanchineMetastaseis and Pithopraktaalong with the earlier Metastaseis. This article about a classical composition is a stub.
