I would advice anyone to only use the ears to find the good sound. That's the best tool. It can also help to record yourself because it's not uncommon to "miss the forrest for the trees".AndrewMeronek wrote: ↑Mon Dec 18, 2023 4:13 amFYI: it pays to be careful about defining just what these terms "undertone", "overtone", and related things like "partials" and "harmonics" actually mean. Unfortunately, there isn't really a clear consensus in any of them, unless you seek out a fairly specific physics context - which musicians are generally terrible at.PiccoloTrombonist1 wrote: ↑Sun Dec 17, 2023 6:04 pm I looked into what causes undertones, and Wikipedia stated that on wind instruments, it’s caused by overblowing, which is how I reached that conclusion.
Use the ears of a good experienced teacher is also a good thing. He can help you to listen for certain things you might not notice yourself, but you then need to hear and fix the problem yourself. Nothing beats your own ears if you want to get better. My best advice is you pay a professional for a couple of lessons, and make shure you tell you need to work on your sound. He should then demo his own sound if anything. Then you need to listen and compare your sound to his.
Until then; Op, can you do that video?
