Abstract. This article analyzes and identifies key similarities in performance techniques in vocal, violin, and piano. The role of a number of performance techniques in high-quality and professional performance is determined: vibrato, resonance, breathing, legato, and vocalization in violin and piano, and instrumentalization in vocal performance. The authors analyze identical performance techniques and similar methods of implementation, demonstrating a certain trinity between vocal, piano, and violin performance. They demonstrate that this multitude of similarities and intersections is important not only from an artistic perspective but also from a practical perspective.

Keywords: vocal art, violin art, piano art, professional performance, vocalization, instrumentalization, vibrato, legato, resonators.
