Ihave seen a statement that Arban`s cornet had a third valve which corresponded to two full steps instead of the standard 1.5 that we are accustomed to. Does anyone have access to an old Arban "bible" with fingering charts? I would be very grateful to have this confirmed or falsified. It is not totally unbelievable, since French tubas often have used two-tone third valves.
