I think there are several wrong ideas in "Clarinet Acoustics", and this is
the most egregious one. With no theoretical backing, and very little
evidence of any kind cited, Gibson insists that overall bore size (or
specifically the minimum bore diameter in the middle of the instrument)
determines the tuning of the twelfths between the first and second registers.
This is just false. I don't know what caused his mistake, but one way to
ensure that large-bore clarinets have twelfths out of tune is to play them
with a mouthpiece and barrel designed for a small-bore clarinet.
