A grand piano is a large, horizontal piano with a curved shape and a full range of keys. Inside, it has a complex mechanism where hammers strike strings when the keys are pressed, creating sound. The grand piano's design allows the sound to resonate fully, producing a rich, powerful tone with a broad dynamic range. It is often used in concerts, classical music, and various other musical genres for its exceptional sound quality and expressive capabilities. The grand piano's size and shape also contribute to its ability to project sound effectively in large spaces.
