A grand piano is a large, acoustic musical instrument known for its rich sound and elegant design. It consists of a wooden case that houses strings and hammers, which produce sound when the keys are pressed. Grand pianos are often used in concert halls, music studios, and homes, making them popular among professional musicians and enthusiasts alike. The instrument comes in various sizes, including the baby grand, medium grand, and concert grand. Each size affects the sound quality and volume. The grand piano is distinct from the upright piano, which has a more compact design and is typically used in smaller spaces.
