Musical expression refers to the way musicians convey emotions and ideas through their performances. This can involve variations in dynamics, tempo, and articulation, allowing the artist to communicate feelings such as joy, sadness, or excitement. Techniques like vocal inflection or instrumental phrasing enhance the emotional impact of a piece. Different genres of music, such as classical, jazz, or rock, each have unique ways of expressing emotions. Musicians often use improvisation or specific stylistic elements to create a personal connection with the audience. Ultimately, musical expression is about translating feelings into sound, making it a universal language.
