In which art form is sound the main medium but visual presentation can change the experience?

Music performance

The governing concept is the distinction between a primary medium and supporting media. Option A is correct because music is organized primarily through sound: rhythm, melody, harmony, tone, silence, and duration carry the central artistic communication. In a live performance, however, stage design, lighting, movement, costume, and the performer’s visible presence can change the audience’s interpretation and emotional experience. Clay pottery is mainly shaped through a material and visual or tactile process, a mural is primarily visual and surface-based, and calligraphy depends mainly on written marks and visual design. These forms may include sound in an exhibition, but sound is not their defining primary medium in the given choices.
