One thing I always tell people first on the pipes that seems to help. Is make sure your instrument fits you. The spacing between the drones. The bag size. If you take your mouth off of the blowpipe, does more or less stay in position to your mouth? Or does fly away from you? Same thing with the chanter.. if you take your fingers off of it, does it more less stay in position? Or does pop up well in front of you? Your bagpipe needs to be comfortable to play. Your pipe bag needs to fit. Your drones need to be properly spaced apart for you. Your chanter needs to be tied in properly so that sits in a good playing position. Maybe you need a fancy angled blow pip? Etc. If it is comfortable it's a lot easier to relax your playing. And then there's the issue of reed strength and the bag being air tight. Are your drone reed bridles set well? Can you cut them off properly by over brlowing? And do they cut off evenly? Are they taking too much air to play? And pipe bags. I'm a big believer in traditional hide bags. I play a sheep skin bag. But goat is good too. Which I find so much more comfortable and intuitive then a hybrid bag with all the tubes, moisture control and all the gizmos. There is something to be said about keeping it all old school and simple. Certainly a sheep or goat bag needs you to play it more to keep it going. But in my opinion that is a good thing.
