There are things I know that I was not taught so for example I can repeat a melody. I can sound like almost anyone by just copying, but I wasn't actually taught music.
I understand song structure as you said. I know the chorus is a verse a hook and a bridge and I understand a semblance of time. I just wasn't taught it. I learned it from standing by the record player and playing it over and over again until it kind of stuck
While I was in choir, they gave me the sheet of music and I just stared at it. It made no sense. But the teacher played it on the piano and I sang it like I heard it
So you're right, I do know some music theory, but the kind of details of the band was talking about in this video I don't understand halves and whole steps and all that stuff, but I can do a lot of it.
Someone was talking about vocal stacking and another person posted this video. This is me all day. I can sing soprano, alto, tenor and baritone
First of all, men don't sing soprano, but we'll get to that.
Second, it sounds like you're confusing being able to read music and understanding music theory. You don't have to know how to read music to understand the basics of music theory. And to keep repeating you can mimic this or that means nothing - no offense.
I can explain it to you very simply.
Imagine you have 12 rocks. They are all about the same shape. 8 of them are bigger than the other 4. Guess what? You've got an octave.
Now let's arrange them like this:
big - little - big - little - big - big - little - big - little - big - little - big - big.
Look at that, there are 12 "steps."
If you go from big to big or little to little it's a
full step. But if you go little to big or big to little it's a
half step.
Not too hard to understand.
Let's see if we can find a visual aid.
Look at that. Make sense?
How about we put some type of marks on them to make it easier for us to explain it to other people?
And there you have it. I can now TELL you what note I want instead of having to show you. And if we want to preserve our ideas, well, that's a whole nother thing called sheet music, but it's no different than you leaving a note for your kids.
Like I said, music theory is like having a bunch of numbers in front of you you can go as far as you want with them. You can stick to 1+1=2 or you can go to advanced calculus - it's totally up to you.
Outside of opera, which has various textures know as "colors" for each vocal range, traditionally there are 6 ranges. They overlap a good deal so the tessitura is considered the true range of the singer, not how far into other ranges they can go.
Bass, baritone, and tenor are the male range. Falsetto or counter-tenor is not considered a natural range.
Tenor, mezzo (soprano) or contra (soprano), and soprano are the female ranges. Whistle is not considered a natural range.
