The history of the ancient piano can be traced back by the 6th century BC the ancient Greek dulcimer, (these two instruments for later generations of ancient pianos and pianoforte have a direct impact on the production of the Pythagorean production), the medieval Persia appeared in the region of the Soltre (plucked) and Dulcimer (strummed), the two instruments, although structurally very similar, but completely different in the way of playing. similar in structure, but completely different in the way they were played. The dulcimer was introduced to China in the 18th century and became the yangqin. In the family of ancient pianos, which flourished during the Renaissance and Baroque periods, there were two main types of instruments according to their articulation: strummed and plucked strings. These are the hammered dulcimer and the harpsichord. However, the most influential of these instruments was the plectrum, also known as the harpsichord, which was favored by composers. The harpsichord is similar in construction to the pianoforte, except that the strings are plucked by bird feather tubes. The harpsichord is also known as the harpsichord because of its large keys

The pianoforte is the predecessor of the piano, which was invented in the 16th century by a musical instrument maker in Florence. Like the piano, it is played by the vibration of tightly wound metal strings. But the difference is that the piano is struck with a hammer a (generally three with the metal wire strings) metal wire string pronunciation, while the ancient piano is made through the feather tube plectrum toggle a metal wire string pronunciation, so there are called "harpsichord" "plectrum ancient piano". Therefore, the timbre of an old piano is thin and the timbre of a piano is thick. In the Baroque period, the ancient piano was the largest keyboard instrument after the pipe organ, so it was also called the "harpsichord". in the late 18th century, due to the old-fashioned tone, the narrow expressive power, and most importantly, it was difficult to play contrasting strong and weak tones like the piano, so it was gradually replaced by the piano in the whole 19th century and was almost forgotten. So it was gradually replaced by the piano and almost forgotten throughout the 19th century. In the 20th century, however, the harpsichord was gradually revived in Europe. The famous Landowska (an authoritative interpreter of Bach's equal temperament in the early 20th century) was a great admirer of the harpsichord.
