The pianistic appropriation of J S Bach prompts a natural question: if we take the liberty
of playing Bach’s harpsichord and organ works on modern concert pianos, are we
not violating the composer’s artistic intentions? And if we commit ourselves to this anachronistic exception on as basic a question as instrumentation, what grounds have we to make other judgements about what is stylistically appropriate?
To what extent should one follow the directions of the score, if the score fails to unambiguously specify the composer’s intentions? Should period-style ornamentation be used, and should it be used throughout the performance? Should all repeats be observed, and how should one treat phrasing with regard to tempo? Where should the musical work dominate the expressive tendencies of the players, and where should the opposite hold true?
These questions are thrown into even sharper relief on this recording of the Goldberg Variations, because the arrangement being played is not of Bach’s doing but rather the Reger edition of Rheinberger’s duo arrangement. Thus, the score upon which the present recording is based is something of a joint effort between Bach in the early 1840s, and Rheinberger and Reger about a century and a half later.
And, as is very much the case, a significant interpretative contribution has been made by the performers themselves: pianists on the southern tip of Africa in the early 21st century.
