Federico Mompou (1893-1987), who studied in France, was a Spanish composer in twentieth century. Most of his works are piano miniatures which present the subtle element and primitive texture. The overtones from the harmony are meaningful and the musical style is full of sensual and spiritual characters. The way he created the music had the local features of Spain and France due to his personal experience.

Cancons y Danzas, has 15 Piano miniatures, was composed in 1921-1972 by Mompou, and in which folk song from Catalan is comprised.

The purpose of this thesis in order to comprehend the way Mompou composed in his early period, I study the Cancons y Danzas NO. 1-4 (1921-1928); analyze the transition of rythme, harmony and so forth between Cancons and Danzas.
