IGOA, Enrique: Torcal for guitar and accordion, 1997 (excerpt) by Enrique Igoa published on 2017-02-28T08:26:42Z The stages of the so called Karst cycle begin with the surface dissolution of limestone and the forming of sinks, which leads to the opening inside the karst massive of deep chasms and galleries, linked together in the form of underground network through which the water circulates, all of which facilitates the occurrence of sinkholes (torcal). The decrease of the hydrostatic level is accompanied by obstruction of the upper galleries and the formation of stalactites and stalagmites. When normal erosion reduces the level of the whole massif the existing karst inner forms are revealed (as in the Torcal de Antequera, Malaga, Spain). As in previous works (Sonor temporis, Anatexia, Jan Mayen, Sueños fluviales [River dreams] or Médulas), I did not wanted to propose in the music of Torcal a direct descriptivism, but rather to find a deep analogy between geological processes, technical procedures used in developing sound materials and logic of musical discourse. Therefore, the origin and treatment of sounds are based on complex musical procedures – conditioned in part by mentioned geological background –, prior work for the achievement of a work in which it is pursued, however a direct, simple, clear and musically formally self-sufficient sound.
