Which keyboard instrument, popular during the Baroque period, produces sound by plucking strings?

The harpsichord is notable for its unique method of sound production, which is achieved by plucking strings. Unlike pianos, which strike strings with hammers, the harpsichord utilizes a mechanism involving a quill that plucks the strings when a key is pressed. This mechanism results in a bright, expressive sound that is characteristic of Baroque music.

During the Baroque period, the harpsichord was a widely used instrument, favored for its capability to produce rich textures and complex counterpoint in ensemble settings. This distinct sound made it an essential instrument for composers and performers of that time.

In contrast, the other instruments listed do not produce sound in the same manner. The piano strikes strings, the organ produces sound by blowing air through pipes, and while the clavichord can produce a soft sound by striking strings with tangents, it does not pluck them. Each instrument has its own unique sound production method and historical significance, but the harpsichord stands out in the context of the question.
