Hello, I made this tool when I started learning the violin and wanted to correct my pitch despite not having a musical ear. I figured it might be useful to other people (:
So, has it helped you "tune" your ear? i.e., are you able to correct your pitch without the tool now that you've spent time practicing with it? I've often wondered about that. I learned guitar at such a young age, that I don't have a good recollection of the process of learning to have a reasonably good ear, or if it was something I already had and had to just learn to listen to. As an adult, I've often gone years wi…
That said, even if the tool doesn't help for the musical earing directly, it can still help to correct the position of your fingers, and that's very important for muscle memory. So instead of training for hours on the wrong finger position because I don't have a musical ear, I can correct myself and properly train my muscle memory correctly.
Well, you're very lucky to have a relative pitch, I think you can still train for it as an adult, but it may require more time and still might not be possible for everyone. Don't take my word for it thought, I don't recall any solid research on the subject.
