There is a certain type of composer, a type characteristic of the culture of our century, with its unprecedented complexities and contradictions. This is the slow and painstaking composer, who eschews all self–repetition, producing a limited number of works. Each one of these works, however, will be a work of real weight and significance. Henri Dutilleux comes to mind as an example of this type; György Kurtág is another. It can be said that these composers, like Varèse, Webern, Spinner, and Ruggles before them, have given us, in terms of substance, a great deal of music. And so has the Slovak composer Dušan Martinček.
