The reed needs to be 'seeing' a longer tube *before* you go through the
high C (because D and above are harmonics of longer tubes). So be sure
to be half-holing far enough down the instrument as you approach the C.

A useful way of thinking about the process of a glissando is that you
need to make the clarinet fingering 'ambiguous', so that the reed's
behaviour is dominated by the mouth cavity, but is partly supported by
this 'ghostly' tube.

So pull all your fingers off a bit, after you get sufficiently above the
D you start on.

(Then you have to work out how to get them back *on* for the high F
arrival;-)

By the way, Abe Galper sent me an interesting article about how the
position of the back of the tongue has to correlate with the pitch
played. I'll write about it when I have time -- but essentially, the
burden of the thing is that the back of the tongue has to go *down* as
the pitch rises. (This was shown with X-ray pictures, and it's what
Howard Klug says in the Clarinet Doctor, too.) But we're not very good
at feeling what we actually do with the back of the tongue, so the
information isn't all that much use to us as we're learning.

It fits in nicely with my 'hipponet' idea, though, doesn't it?

... We all have failures. The question is, what do we do with them?
