Estonian composer Arvo Pärt’s Tabula Rasa surprises us for its apparent simplicity yet forceful emotional content. Tabula Rasa features two violins, piano, and orchestra. Linked here is the 4th section.[audio:http://www.thegnosticoracle.com/MP3s/Tabula_Rasa.mp3|loader=0x9900ff]
The composer describes his music as tintinnabuli, or a ringing of the bells. His influences range from neoclassical to medieval chant to Schoenberg and the 20th century minimalists. Attempts to categorize Pärt trend to sacred- or holy-minimalism; his work often contains Christian motivation and text and is rhythmically simple and often mathematically derived. He was born in 1935.
