but doesn't the clarinet produce only odd-numbered partials (starting
with the fundamental as the first)?

The odd-numbered partials predominate, yes, but the even partials are
still there. There is an interesting set of 4-color spectral graphs
at:

http://hughes38.som.ohio-state.edu

that were done by James Pyne (who makes mouthpieces). In general, the
even partials are about 3/8 to 1/2 of the odd partials when displayed on
(I believe) a log scale --- which means much steeper slopes when
displayed on a linear scale.

Just to be very explicit about this, I don't have direct knowledge of
how a tuner works or which parts of a harmonic vibration recipe it looks
for. Since the same tuner is supposed to work for sax, flute, piano,
harp, etc, there must be some latitude in the criteria.

As an after thought, I wonder if my tuner would have similar confusions
with an English horn, which also has a spherical bell?
