Extended data:
In Europe, between 14 and 18 centuries, two kinds of keyboard instruments were popular, one called harpsichord and the other called harpsichord. These two musical instruments are called clavichords because they are considered as the predecessors of pianos. Many composers composed music for the clavichord, and the music at this time was the earliest piano music.
For example, Bach, Handel and scarlatti's piano music are all written for the clavichord. Many works by Haydn, Mozart and Beethoven were also written for the clavichord. In addition, the clavichord has its own delicate timbre. Therefore, after the clavichord was generally replaced by the modern piano, at the turn of the 19th and 20th centuries, and even in contemporary times, a few pianists advocated the use of the clavichord. Until modern times, many types of electronic organ have also set the timbre of the ancient piano.
