By the turn of the century and for the next few decades, artists of all nationalities were searching for exciting and different modes of expression. Composers such as Arnold Schoenberg explored unusual and unorthodox harmonies and tonal schemes. French composer Claude Debussy was fascinated by Eastern music and the whole-tone scale, and created a style of music named after the movement in French painting called Impressionism. Hungarian composer B'el a Bart " ok continued in the traditions of the still strong Nationalist movement and fused the music of Hungarian peasants with twentieth century forms.
