Five superb poetic preludes, form romantic inspiration. Prelude No. 1 was composed in 1945 and Prelude No. 2 in 1950. In the first opus, from the outset, the harmony is established through the degrees of tonic, subdominant and dominant, and then begins a transition to A minor. The second one begins with a repetitive motif interspersed with triads of D major and C major. An extension of the phrase brings in more harmonies and leads to a repetition of the first bars, transposed a major second above.
