Hello, Israel.

Here's an article which explains what the system is about

http://en.wikipedia.org/wiki/Tonic_sol-fa

However, I can't find anything that shows anybody actually using the system. You may need a music teacher for that.

For me personally, the system seems to be of no use at all.
I can hear tunes, remember them, sound them out and harmonize to them, but if you ask me if a tone is do or so or ti, I couldn't begin to tell you.
