Keith Jarrett's album, Book of Ways, was recorded on July 14, 1986 in Ludwigsburg, Germany. Rather amazing is the great variety of sound and rhythm - Jarrett played alternately one or two instruments simultaneously. Beyond unmistakable echoes of lute music and Japanese koto, the whole range of modes of expression the clavichord is capable of is being fathomed out. All this has been supported by studio techniques, which recorded the sound of the instrument with rarely heard intensity.
