The edition is supplemented with a facsimile of the autograph.

As well as being a bibliophile´s delight, the edition also offer the opportunity to study the composer´s own manuscript in all its details. The most subtle nuances, which can only be represented in musical handwriting and never in print, can thus provide a logical extension of the typographical limitations of engraving, and convey additional stimuli for consideration of the interpretation of the work.
