"Sonata from Two Notes" by Elena Poplyanova possesses unusual properties. It gives the performer a rare opportunity to look into the most countersunk corners of composer's creative laboratory.Two careless notes as mosaic details form a theme and the image revives. It is so changeable and dynamic, that the reincarnations may be observed infinitely. Disintegrating and developing a new image the theme seems to try on different masks: those of villain and virtue, lyric and grotesque characters... As the blast of the wind makes the paper mosaic details scatter in different directions, so do splinters of the theme fly asunder all over the keyboard by the ending of the Sonate.The sonata's ending brings us back to two notes with the help of which all has begun. Only now they don't seem to be so ingenuous.
