“But Carter, you said E♭ major and C minor share a key signature and there is definitely a C minor chord in this song. Isn’t this song then in C minor?”

An instrument’s strings are never perfectly in tune, and even the best violinists don’t place their fingers on the exact right place on the fingerboard. By alternating these two wonky A’s, Bach is drawing our attention to the physicality of the instrument, and to the way that the subtle microtones you get from physically playing it rub uncomfortably against each other. Guitarists use this same technique all the time, and it’s no big surprise that the chaconne sounds so great on guitar.
