[1] Many people are familiar with the piano, but not everyone knows that it represents the evolution of keyboard instruments developed over several centuries. The piano is just one of many types of keyboard instruments used by musicians throughout history. [2] Keyboard instruments have been in use since the 1300s but did not become well-established among composers and performers until somewhat later. In the 1500s, for example, a keyboard instrument known as the harpsichord rose to prominence. It is one of the earliest kevboard instruments to become favored by musicians and comnosers of Western classical music, for both solo and ensemble (eroun) olavine. In The author presents information using a chronological structure in paragraph 2 and a compare/contrast structure in paragraph 3. Are these structures effective in supporting the author's thesis that musicians have used many keyboard instruments throughout history? 1. No, because only the chronological section supports the thesis. It shows the prominence of several instruments, while the compare/contrast section focuses primarily on the differences between the two. 2. No, because only the compare/contrast section supports the thesis. It describes how the keyboard instruments were alike, while the chronological section merely lists popular instruments. 3. Yes, both structures support the thesis. The chronological section explains how keyboard instruments developed over time, and the compare/contrast section places them into distinct categories. 4. Yes, both structures support the thesis. The chronological section provides interesting details about the piano, and the compare/contrast section emphasizes similarities between the piano and the harpsichord.
