Im more than willing to wait but im just working the leadpipe/sound column in the second stage – scale and arpeggio but was having some issues going to the full octave or above with either scale or arp.. I was trying to use absolutely passive breath and only MOUTH manipulation – which was what I thought you meant by shape. When I started to flick or do something with the tongue (certainly not anchor tongue!) I finally saw the partial pop out without the push. Is the tongue included in what you call shape. I really want to understand shape better, but I know the program is progressive.
