自由作曲途径中的潜调性思维——徐昌俊的手风琴独奏《两首前奏曲》探析

Latent Tonal Thinking in Free Composition——Analysis of Xu Changjun’s Accordion Solo Two Preludes

徐昌俊的手风琴独奏《两首前奏曲》由深圳"福田杯"国际手风琴大赛组委会委约,创作于2019年。第一首标题为《小步舞曲——幽默的小快板》,采用"四音动机"贯穿发展;左手以"线性"进行为主,右手采用对比的节奏型,双手始终交错对比、平行发展一直到结束。第二首标题为《无穷动——火爆的快板》,采用全新的对比主题,密集展开、扣人心弦;第一首《小步舞曲》的"四音动机"被"有意"地安插其间,若隐若现,突出了两首作品的内在联系。

Xu Changjun’s accordion solo, Two Preludes, was commissioned by the Organizing Committee of Shenzhen "Futian Cup" International Accordion Competition in 2019. The first, titled Minuetto—a humorous little allegro, uses a "four-tone motivation" throughout its development;The left hand is given priority to by "linear", while the right hand adopts the rhythm of contrast. The hands are always staggered and contrasted, and develop in parallel until the end. The second is titled Movimento Infinito—the popular Allegro, using a new theme of contrast, intensive expansion, exciting;The "four-tone motivation" of the first "Minuetto" is "deliberately" placed in the middle, faintly visible, highlighting the inner connection between the two works.
