Well, I was shooting about in the dark here looking for whatever would get my head working on this again... I stubled across a CD called "Blues in a Sharp Sea" (by an interestingly named band... And G1 does feature a "sharp" C with a blue thing in it.) which made me wonder about sharp C's and what have you, which lead me to music. C1 is more often called Middle C (not sharp at all, unfortunitly). Where am I going with this? I have no idea. Perhaps someone else might find it of use, though.
