Erno Lendvai was a pioneer with his book Bartók’s Style (published originally in Hungarian in 1955) in the research of the great Hungarian composer who obviously had one of the major influence on the 20th century music. He gives an analysis of tonal organization, proportions, interval symbolism, polarity and other aspects in two twin compositions: Sonata for Two Pianos and Percussion and Music for Strings, Percussion and Celesta.
