I wonder if it would be easier to actually hold a note higher than a Low C for longer than one could hold a Low C for.

Less air travels through the instrument the higher we play. I’m not suggesting one could hold a Double C for longer than a Low C, but I wonder what the easiest note may be.

I doubt it’s low F# (123)–I suspect that note would be harder to hold for as long as a Low C.

But I wonder if G on the staff might be easier to hold than even a Low C.

Might be a very interesting experiment…
