The clavichord, invented around 1400, emerged as a quiet keyboard instrument with tangent action, allowing for expressive playing. This instrument played a significant role in the development of Western music, serving as a practice tool for composers and musicians. The clavichord's unique sound and mechanics influenced the design of later keyboard instruments, including the harpsichord and piano.

The invention of the clavichord in 1400 allowed for intimate musical expression, influencing the performance of lieder and poetic songs. This instrument became a symbol of personal expression in poetry, reflecting the emotional depth of human experience and the interplay between music and verse.
