Do Mi Sol

In English, C E G is popular?
Since I was a young, ah, elementary school something, I know Do Re Mi Fa Sol la Si Do.
So, I mean, we are custom, mmm have custom??, for C major scale.

In case of C major, Do Mi Sol is very important? Right?
Do and Sol are good relation. Mmm, I can't explain more, yet, though.

And, if Mi came down half note, it will be C minor.

Mmm, anyway, I don't know why, I like Mi, maybe. :)


I'm playing with such like this, these days.

What tone, what note, do you like? Sol? Or Si? Or Re? :D
