Three Préludes for Piano - No. 1 Allegro ben ritmato e deciso (为钢琴而作的3首前奏曲 - 第1首 热情且坚定的快板)-Mario‐Ratko Delorko

The first prelude, in B-flat major, begins with a five-note blues motif; virtually all the melodic material in the piece is based on this theme. Syncopated rhythms based on the Brazilian baião and chords containing flattened sevenths occur throughout; these give the piece a strong jazz feel. Although these sounds are far from adventurous by modern standards, to the audiences of the late 1920s they were almost unheard of. Structurally, the piece is in ternary form; however, the impression on the listener is that of a fantasia. This effect is achieved by using snippets of various virtuoso techniques, such as repeated notes, octaves, scales, and crossed hands, each of which is used for only a moment before the piece catches a flicker of some new idea.
