Cristofori's invention was further developed by other instrument makers, including Gottfried Silbermann and Johann Andreas Stein, who made significant improvements to the design and construction of the piano. By the late 1700s, the piano had become a popular instrument in Europe and began to spread to other parts of the world. The first pianos in the United States were imported from Europe in the early 1800s, and soon after, American piano manufacturers began to establish themselves.
The piano continued to evolve and improve throughout the 19th century, with advancements in materials, construction techniques, and design. By the late 1800s, the piano had reached its modern form and became widely used in homes, concert halls, and other musical settings. Today, the piano remains one of the most popular and versatile musical instruments in the world.
