Well, it's not actually about András Schiff - his name is highlighted in the beginning of the article and there is a quote by him and then the writer goes on to other things. I stopped reading after the part about singers breathing into the belly because that is only half the mechanism, and it's that kind of thing which created tension for me at some time. Above all, if someone is going to learn breathing techniques, it should not be by writing a few short sentences and then trying what he understands (and what the writer might understand).
