【摘要】 音乐美学与音乐哲学的学理分歧,长期建立在“作品本体论”的共同前提之上:前者以作品引发的感性经验为中心,后者则将作品视为意义生成与主体展开的场域。人工智能在音乐与音声领域的发展,使这一前提首次在现实层面受到根本挑战:当音乐可以在缺乏具体生命经验的条件下持续生成,作品不再天然指认主体在场,由此引发的并非单纯技术或伦理问题,而是一场符号与主体的结构性危机。文章从人类符号发展的历史结构出发,将这一危机理解为符号进入自我生产阶段后“主体空场”的体现,并指出:该变化对科学符号影响有限,却直接动摇了艺术以确认个体经验为核心的功能。在此背景下,艺术不再通过作品确证主体,而转向通过激活个体的感受、想象与生成活动来维系其存在。据此,文章将当代转向界定为“艺术即人,人即媒介”:艺术不再是对象化产品,而成为个体在虚实相间世界中生成意义的存在方式。在这一转向中,音乐美学与音乐哲学得以在更深层次上重新汇合,共同回应人工智能时代关于主体、经验与艺术可能性的根本问题。更多还原

【Abstract】 The theoretical divergence between music aesthetics and music philosophy has long been grounded in a shared premise of the " ontology of the work" :the former centers on the perceptual experience elicited by the work,while the latter regards the work as a field for the generation of meaning and the unfolding of subject.The development of AI in the domain of music and sound has,for the first time,fundamentally challenged this premise on a practical level.When music can be continuously generated in the absence of concrete lived experience,the work no longer naturally signifies the presence of a subject,triggering not merely technical or ethical issues,but a structural crisis of sign and subject.Proceeding from the historical structure of human sign development,this paper interprets this crisis as a manifestation of the " absence of the subject" after signs have entered a stage of self-production,and points out that while this change has a limited impact on scientific signs,it directly destabilizes the function of art,which is centered on affirming individual experience.Against this backdrop,art no longer confirms the subject through the work,but instead sustains its existence by activating the individual’s activities of feeling,imagining,and generating.Accordingly,the paper defines the contemporary turn as " Art is human,human is medium" :art is no longer an objectified product,but a way of being in which individuals generate meaning in a world that blends the real and the virtual.Within this turn,music aesthetics and music philosophy converge anew at a deeper level,jointly responding to the fundamental questions concerning the subject,experience,and the possibilities of art in the age of AI.更多还原
