"The study of transformational processes in contemporary music art under the influence of the fine arts practices is one of the important problems of musical culturology and aesthetics. The study is topical because of the new efforts aimed at understanding and arrangement of the evolution of established aesthetic systems and experiments in music and fine arts in the 20th century and at the beginning of the 21st century, as well as their influence on modern practices of introduction of meaningful elements of painting, graphics, architecture, and multimedia technologies into music creation processes. The aim of the research was to identify current trends in music visualization through the arrangement and generalization of the experience of artists of the 20th — early 21st centuries, who used expressive arts, synthesizing one art into another in their musical compositions, as well as to identify the background of those synthetic ideas and ways to implement them. The scientific research established that the development of synthetic art has its roots in the disposition towards merging arts and versatility. The fine arts practices applied in music has contributed to the expansion and enrichment of artistic means and techniques and has entailed further complication of sound and visual components in the overall concept of the work. It is concluded that the individual creative and personal traits of the artist, who seeks to fully convey the multidimensional figurativeness of the work determine a significant impact on implementing fine arts practices in music. Prospects for further research of the evolution of fine arts practices and audio-visual media in music involve the development of description techniques in the context of the dominance of the visualization factor over music one in artistic perception, as well as the study of the impact of cultural technologization on contemporary music art.
