Hi Dave, If that helps you then that's great - anything that helps to understand the sounds we make is good. But, strictly speaking, Do Re Mi... are the Italian versions of C D E... so have the same problem as using the note names in English. Using numbers bypasses this in both of those situations though, so it's a useful idea to try out :)
This is what I am looking for and it's really the most essential practice that no one tells me. I could play some music and read scores but I have never been confident. I was not able to find the reason but I think I finally found it. This essential ear training is the really matter to me!!!
Great videos -- I'm looking for videos with all the intervals (including minors, tritone etc) for all the scales with the alto saxophone sound. That you.
