B isn't really so low as a didge but it is beginning to get into that range where getting a good instrument is much more difficult. There's a lot to understanding how to get the right type of backpressure and a big satisfying dynamic, especially in a reasonably sized instrument. This B is an example of everything coming together exactly right. Normally I'd recommend a C to E for a beginner but this B is super easy, and the deep timbre of the wood combined with the low note of the B conjures the magic that draws us to the didgeridoo in the first place.
