I think arthurpianist meant a book that develops a technique such as arpeggios, repeated notes, scales, chords, etc. While there are such books the best way to learn is with a teacher. One would not use the same wrist movement or staccato while playing Bach or Chopin for example. The best way to learn is through a teacher and a book might not cover some of the technique. As for technical material, there are scales, arpeggios, chords, etudes, and pieces that develop technique of course. There might be many books that explain technique, one shouldn't be restricted to just that technique. For example, as I am learning the Bach's preludes, I use 2 editions that both have their points, whether fingering, dynamics, etc. The point is, using a variety of sources, whether technique or pieces, will be better than just using one particular.
Best Wishes to all.
