There is SOME pattern, and this can be appreciated by trying to
overblow harmonics without (preferably) the speaker key. For instance, if
your reed co-operates, it's fairly to overblow the chalumeau C to produce
G, E, and the altissimo A, which is a flat seventh harmonic - most of the
really high notes are flatter than one would expect from just looking at
the harmonic series. (This is much easier on the bass clarinet - sometimes
much too easy...).So altissimo A-C ("normal" fingerings) work out to be
flat seventh harmonics of chalumeau C-E flat. There are a lot of
fingerings which cannot be fitted into such a pettern, though, especially
most of those for high G and G#.
