The predecessor of the piano was the plucked clavichord, also known as the harpsichord. It is much the same as the internal principle of the piano, which is equipped with a soundboard and many taut strings inside the body. The difference is that the piano's hammer strikes the strings, and the plucked clavichord uses a plucked plectrum to pluck the strings. In addition, there is a keyboard instrument of the same lineage, the clavichord, which is also an instrument equipped with a percussive device, and is pronounced with a brass mallet; It was not as widely used as the plucked clavichord, and was mainly played in aristocratic families at the time. In the 17th ~ 18th centuries, the plucked piano had a very prominent position in the musical life at that time, and it can be said that it was its heyday. By the beginning of the 18th century, the music of continental Europe was developing rapidly, and the plucked claviest piano with weak volume could no longer meet the needs of musicians at that time, so it was gradually replaced by the loud piano.
