4 short piano pieces for the pianist in the medium-advanced level. In these pieces Nico Dezaire used some of the composition techniques, used in the 20th century. In Part 1, "Inventio" it’s bi-tonality, chords consisting quarters and variable metric. In Part 2 "misterioso" you will find the gamelan-structures of Claude Debussy, and the idea of new modes of Olivier Messiaen. Part 3, "scherzo" is a bright and biting piece: a round ostinato rhythm/interval a la Bartok is the basis over which Nico Dezaire paraphrases 2 Dutch folk songs. In Part 4 "finale " certain elements of the preceding movements return and we hear a mirror canon in fifths, instead of the usual thirds and sixths, an idea again of Bartok.
