How is the principal theme constructed in this piece?

The principal theme in this piece is constructed using three short notes followed by one long note. This arrangement creates a rhythmic pattern that captures the listener's attention and establishes a memorable motif. The use of short notes injects energy and movement, while the subsequent long note provides a sense of resolution or emphasis, effectively balancing the structure of the theme. This specific pattern enhances the thematic identity of the piece, setting it apart and making it easily recognizable. In musical composition, variations in note length play a crucial role in conveying emotion and creating dynamic contrast, which is exemplified in this choice.
