Metamorphosis / Bartok, Kodaly, Ligeti

It is sometimes said that the essence of ‘classical' music lies in the principle of variation; but when the idea of incessant transformation of the musical material irrigates scores like these quartets by three eminent Hungarian composers of the 20th century, the resulting sonic impressions are very different. The governing principle here is metamorphosis, an idea as dear to Bartók as it was to the compatriots who succeeded him.
