Mic'l, one of our resident harp-tilting lipblockers wonders:

I think this can be an important factor in discouraging the reed which would normally play from doing so, thus enabling the other reed to play in opening-reed fashion. For bends, I know it is dispensable, since they can be done with wonderful control and strength by changing things only in the throat (when I tongue-block). For overblows, this effect of air direction (or SOME effect that I can only bring about with the tongue in certain positions) seems more central to my success.
