>From what I'm beginning to remember, the reed
is initially vibrating at its own frequency immediately after attack by
the tongue - the air column then *forces* the reed to vibrate at its own
or some compatible frequency. Given the difference in the materials, it is
hard to believe that the reed at this stage is vibrating in exactly the
same modes as the air column, though. Again - what happens with
multiphonics?
