Clavichord

The clavichord is a European stringed keyboard instrument known from the late Medieval, through the Renaissance, Baroque and Classical eras. Historically, it was mostly used as a practice instrument and as an aid to composition, not being loud enough for larger performances (a problem that was solved when the Clavinet was invented in the mid-20th century). The clavichord produces sound by striking brass or iron strings with small metal blades called tangents. Vibrations are transmitted through the bridge(s) to the soundboard. The name is derived from the Latin word clavis, meaning "key" (associated with more common clavus, meaning "nail, rod, etc.") and chorda (from Greek χορδή) meaning "string, especially of a musical instrument".
