VII. Read the following passage carefully, and then select the best option A, B, C or D to complete it.
Music, artful arrangement of sounds across time. This definition is obviously very broad, but a narrower one would exclude too much. Music is part of virtually every culture on Earth, (26) it varies widely among cultures in style and structure. Definitions of music can change dramatically over a short time, as they have across the world during the 20th century.
Can music exist without sound? Some philosophers argue that music should be defined as a kind of “mental image” and that the (27) aspects of sound are simply by-products of this image. If you think you can have a musical experience by imagining the sound of a piece of music, then you think music can exist without sound. But most musical experiences (28) producing or listening to physical characteristics of sound such as pitch and timbre (quality comparable to texture or color in sight).
Is the tape recorded sound of a large metal-stamping machine music? Are 4 minutes and 33 seconds of silence music? Is the activity of reading a list of hundreds of (29) unrelated objects, activities, and states of mind music? Each of these “works”, as well as many (30) sounds (or nonsounds), has been copyrighted as a musical composition, performed, and recorded in the 20th century. One of the legacies of 20th-century music is to have blurred the definition of music as never before.
