After repeated prodding from my teacher, the other day I finally bought a manuscript edition of the Sonatas and Partitas for solo violin (for the non-musicians: Bach's handwriting is astonishing, but not that bad once you get used to it; go
here for an example). Once I started poking around in it I was delighted to discover that some of the bowings that I've always thought were a complete crock and that show up in every bloody edition of the things ever printed - including the one attached to the facsimile I bought which purports to accurately transcribe what J.S. wrote, hello, do you have eyes? I thought not - are in fact not Bach.
VINDICATION!
