As I understand it, the shape you get if a cartoonist wants to depict a drop of water: pointy top smoothly widening to rounded belly shape, and in my mind, the top is not straight but bends off to the side the chanter's going to go. Again, like the cartoon drop of water. If I'm wrong, someone

Hello Richard, Many NSP bags can be slightly rectangular in aspect and the 'corner' near the blowpipe has the potential to annoy some players. If you find that experimentation in managing the bag differently does not help, a good solution would be to order a bag with the profile of that edge

Hi Richard, Other slight annoyances occuring when messing with bags/neck is resonance or a change in the resistance to airflow. Some bag/neck shapes give rise to top A and top B sounding flat at which point the unsuspecting will start chopping or scraping reeds - BEWARE Dave Singleton

I always understood the point of the open-cell foam in the neck is to remove the neck resonance problem referred to earlier. The frequency of this resonance depends critically on the shape - if you model the bag as a big cavity with a narrow tubular neck,like a bottle, the formula
