If you watch the vid again (and listen carefully) at the end you can hear some "bebung" which is on the very last chord and is vibrato caused by slightly varying how hard you wobble the keys after they have been struck.
The clavichord has strings that are struck by a piece of metal called a tangent, so extra prog-points there too.
