I only ever learned the basics of the major scale syllables, mostly from the "Doe, a deer" song.
In C Major,
- Do - C
- Re - D
- Mi - E
- Fa - F
- Sol - G
- La - A
- Ti (or Si) - B
- Do - C
So how do you augment this framework with the black keys?
I suppose here, I'm referring to a "Fixed Do" anchored to middle C, but I think (hope) it applies to a "Movable Do" as well, relative to the current tonic.
