Scordatura

One of the things about Just Intonation on a cello is the fact that the strings are tuned in perfect fifths, which means that if you take C as your 1/1, the A string's actually too sharp. So here I detuned the A string by 80/81. I did this by stopping an E on the D string (tuned to make a just sixth with the G string) and then tuning the A down so it made a perfect 4/3 with that.
