Wow! Thanks guys. I slept on this thread and am so glad I just noticed all of the kind and useful responses! I’ve got some time off coming up and SEVERAL melodicas that can use some tuning. I’m going to practice and use the video supplied here. I’ll prob damage a few but they aren’t really useful as is now. I very likely will check back when I have enough experience to offer a specific and (hopefully) intelligent question. Thanks again for all the feedback! – Tom
