Would midday be middle C ?
Ah! Sort of, I see what you mean, I meant 12 bells which rang down in sequence. So 1 o'clock would be, for example middle C, but 2 o'clock would start with D, then C. 3.00 would start on E, then D, then C etc. The higher the first note, the later it is.
Does rely on the listener knowing what the bottom note (the 1) is, and having perfect pitch to determine the number of notes above it the first bong is.
Maybe it's not such a good idea. I have lots of those, not so good after all ideas.
