This paper aims to examine the similarities and differences between Bordun and Stufen in Carl Orff’s Die Weihnachtsgeschichte (1948) and Musik für Kinder (1950-54). Following his studies of the music of the Middle Ages, Orff’s musical style developed in a distinctive way, as evident with such works as Carmina Burana (1937). His musical style led to his philosophy of elementare Musik as an educator. An understanding of Orff’s educational philosophy is therefore important when investigating his creative and educational activities. Die Weihnachtsgeschichte is a work Orff completed after he became involved with child education, which based on his practice at the Günther-Schule. After Orff’s success with Carmina Burana, he made text of Die Weihnachtsgeschichte and Gunild Keetman composed that music. Following Carmina Burana, Orff developed an original musical style and composed mainly works for the stage, and his creative and educational activities have to be explored in the light of this background. With respect to such activities, this paper examines the musical features in Die Weihnachtsgeschichte with a particular focus on Bordun and Stufen, which are two of Orff’s typical methods. This study also investigates the use of Bordun and Stufen in Einführung Musik für Kinder. The techniques of Bordun are based on three features. With Stufen, I identify the following features: (1) chord progression; (2) use of the dominant; (3) chord-based modulation between major and minor.
