阅读下列短文,从每题所给的 A、B、C、D 四个选项中选出最佳答案。
A
Different instruments, different voices
Music is a universal language, and instruments are the tools that speak it. Each instrument has its own voice and character. Understanding these differences can help us appreciate music more deeply.

The piano is often called the "king of instruments". It has 88 keys that produce both melody and harmony. A pianist can play loud or soft, fast or slow, all with ten fingers. The piano’s wide range makes it suitable for almost every style of music, from classical to jazz.
String instruments like the violin and the cello create sound through vibrating strings. The violin is small and bright, often carrying the main tune in an orchestra. The cello, however, is much larger and produces a deep, warm tone. It usually supports the harmony beneath the violins. Though they look similar, their voices are worlds apart.

Wind instruments use air to make music. The flute produces a clear, light sound that floats like a bird. In contrast, the saxophone has a rich, powerful voice full of emotion. Players must control their breathing carefully. A steady flow of air is the secret to a beautiful tone.
Percussion instruments(打击乐器) keep the rhythm. Drums and xylophones(木琴) may seem simple, but they are the heartbeat of a band. Without them, other instruments would lose their sense of time and energy.
No single instrument is better than another. They are like colours on a painter’s palette. Only together can they create a complete and beautiful picture.
