I am working on the Bach C minor Sonata for violin and harpsichord, BWV 1017, which I am performing with piano next month. Rather than try to pretend the piano is a harpsichord, and that I am playing a baroque violin, our approach is to play the piece as well as possible using modern equipment. I have been futzing with the bowings of the opening Siciliano, seeking out alternatives to the printed bowing, which I imagine is not Bach's since the edition we are using is not an urtext.
Last night I decided to tape record myself, and to my horror and shame I found that I was making all sorts of false accents, and I failed to sustain dotted rhythms properly when I applied bowings that I thought were "stylistically correct." I tried bowing the passages in question in several different ways, and my tape recorder revealed glaring errors with each bowing alteration. Then I tried the "inauthentic" printed version, and my false accents and rhythmic instability disappeared. My guess is that this part was edited by a very smart violinist who knew how to make the violin do what the music asked it to do.
