I’ve been learning a few basic tunes on the practice chanter, but I cannot play them on the bagpipes. I’ve got all my drones corked so I can focus on learning how to properly adjust the air pressure. I can blow the low hand notes pretty well for several minutes. My issue is that whenever I try to play a B doubling or transition from high hand notes to low hand notes, everything stops. As soon as I play a G Gracenote, the chanter shuts off. Is there something related to air pressure that I’m not understanding or is this an issue common to beginners?
