Hi thanks,

Just to elaborate a bit more, I wasn't talking about C major scale, I was talking about the C Major Chord that I learned on the first lessons from the level 1 Fundamentals for example.

So, what I mean is that this C Major he knows it as Do

The D Major chord he knows it as Re

E Major he knows it as Mi

and so on and on

So music chords are universal but it will be tricky to talk to someone else if I call a chord C major while other people called them Do and so on.... shouldn't the names be all the same worldwide?

The C major scale consists of 7 ascending notes starting from the root note, CDEFGAB(C) ending again on the root note C. That's how you should learn it.

Right now, the backstory on solmization is really just nice to know but superfluous information when you've other more relevant things to assimilate. If you follow the syllabus and maintain focus, you'll learn what you [u]need[/u] to know.

Technically though, your friend isn't incorrect re assignation of the syllables Do Re Mi etc to the C major scale. More here about it here, which explains it better than the Wikipedia entry.
