I have been working more on my highland pipes in G. The tonal quality was much compromised with earlier iterations with very heavy taping on E and C leaving not much of those holes uncovered. I have since had the idea to actually insert tacky putty into the chanter bore against the inside wall to narrow the bore around those notes and therefore flatten them. No tape is now needed on E, though C still needs some to bring it down to C natural in addition to the ~15 cents it needs to be flat to be in tune against G drones. Think of it as the opposite of carving a chanter. I do notice that the chanter cuts out more readily than before, undoubtedly caused by the bore restrictions introduced by the putty. However, it’s good practice for keeping the pressure up and allows the C and E notes to sound much more clearly. The E note is a little wonky against G drones being a 6th, I think I need a different just intonation value to tune it against. Maybe?
