阿根廷作曲家希納斯特拉的創作生涯起於民族主義音樂，即使民族主義音樂於當時已在古典音樂中流行一段時間，在阿根廷境內卻非流行長久，但希納斯特拉的諸多作品仍然以民族文化素材與新穎創作手法的結合展現出獨匠巨心的作品，成為推銷本土又名響國際的成功音樂推手。當中被歸屬於主觀民族主義時期的《南美大草原第二號》勢必涵納了作曲家精心糅合後的阿根廷民族文化，更不乏其個人的創作特色與具前衛性的技法。本文將針對《南美大草原第二號》作分析與探討，試圖獲知作曲家於當中所蘊含的阿根廷民族音樂素材以及其運用到的特殊創作手法。 The Argentinean composer, Ginastera, embarked on his musical composition path by employing a nationalistic style, despite the fact that nationalism had been prevailing in classical music for some time but not in Argentina. Many of his compositions are ingeniously integrated with national cultural elements along with an innovative approach which successfully launched his music into international status while promoting his country. Among his compositions, Pampeana No. 2 was composed in his "subjective nationalism period," in which he deliberately and eloquently blended Argentina's nationalistic elements with his individual compositional characteristics and avant-garde techniques. This paper investigates and analyzes the composer’s compositional techniques by focusing on Pampeana No. 2. It attempts to uncover his unique compositional approach while unveiling the blending of the Argentinean national musical elements.
