As Jarrett stated in an interview with pianist
Ted Rosenthal appeared in the Jan-Feb 1997 issue of "Piano and Keyboard magazine": "That whole recording was done in one afternoon and everything was a first take and nothing was coming from any pre-ordained thing. I had no material.... I think
Book of Ways is one of the recordings I wish more people would know. I think it has more of what I hear on it than a lot of things (I do) on piano because piano is piano. These two clavichords together made a different instrument. You could use vibrato on one of them and not the other one, and play unison. I was playing two at the same time as you probably could tell.In the original liner notes for the compilation album "Keith Jarrett Selected Recordings", with music selected by Mr. Jarrett himself, he states that:A Note on
Book of Ways: To my knowledge, this recording is unique in several ways. We had three clavichords in the studio, two of which were angled together so that I could play them both simultaneously, and the third off to the side. Also we miked the instruments very closely so that the full range of dynamics could be used (clavichords are
very quiet and cannot be heard more than a few feet away). The two CDs were made on an off day between concerts with my Trio, and no material was organized beforehand. Everything was spontaneous. The recording was done in four hours. ==Reception==
