Right, and I expect to change tunings often as well. Right now I'm practicing my re-working up Bach's Prelude, Fugue and Allegro with a tuning from 8th to 1st of A-D-E-A-D-F#-B-E. I raise the 8th string up to B for the First Lute Suite [Em] and the Chaconne [which I am now playing in Bm]. From that tuning I lower the 7th string to C# for the Fourth Lute Suite [E]. I find I can still go back to the 6-string when needed [though I would not dare play the aforementioned pieces on it again] but find it less satisfying than it once was, if nothing else I miss the 8-string's overtones.
