It has occured to me that a keyboard (with middle C noted) could be placed on the list homepage with the names of the keys on each key. This could be Helmholtz or whatever system desired and all "list-ers" would be referred to the homepage so that the terminology for the list would be consistent.
This would take a bit of trouble on someone's part, but with all the different systems out there, for list purposes, this would eliminate confusion.
Just my thoughts on that...
