Circular breathing is easiest to accomplish on the didgeridoo. This is because of several reasons: optimal back-pressure (hits the sweet spot between lack of resistance on a flute and too much of it on an oboe, for example), loose embouchure (relaxed lips make it easier to puff up the cheeks) and single drone focus (no distracting fingerings required).
replyI also suspect the intense vibrations have a similar effect (probably stronger) to humming, which is known to dramatically (15-20x) increase the release of beneficial nitrous oxide in the nasal passages.
would oboe be more effective then, albeit harder to will-power yourself into mastering?
reply> I also suspect the intense vibrations have a similar effect…
replyMy gut says that there are some interesting discoveries waiting around the intersections of frequency of vibration, individual resonant frequency, and duration
the study was conducted using a didgeridoo but the circular breathing seems to be the important mechanism. No studies have been conducted on other instruments that require or benefit from it.
replyI doubt many of them actually figured out how to circular breathe after one lesson. Source: have been playing sax for 20 years, tried learning it many times, still no good.
replyAulos it is then!
