Lads and Lassies,

I suspect we are all over-complicating the whole process. Buzzing causes the sound, big buzzing causes BIG sounds, little buzzing causes LITTLE sounds - this will also be the mechanism to vary frequency. Tubing shapes, lengths, materials, thickness, coatings etc all alter the sound output either to your liking or not - end of story (I think).

ROWUK is correct (in my opinion) in that blowing allows us simply to breathe, and to create the buzz.

BTW - standing waves are a function of supersonic airflow - that is air travelling higher than the local speed of sound and the shock wave that stands at the point where the speed of sound is achieved (a bit of a simplification). So this too is probably either a misnomer or some other concept misunderstood or "poorly" described - we certainly don't want, and are highly unlikely to achieve supersonic airflow with our breath. A sneeze, for example, gives an output of about 120 mph (from memory).

Once again, I hope this helps. Interesting thread though, keep asking questions, it staves off Alzheimers.

Regards,
