How can I understand what a "six-tone" is when I don't understand music theory?

Let me see how much you can understand.

China's traditional music has five tones, "Gong Shang Jiao Zheng Yu".

Corresponding to "Do Re Misola" in the staff (12356).

They are called orthography.

And the antonym of "orthography" is "partiality"

Deviation of Chinese classical music

One * * * has four.

Like "Do Re Mi Fa So La Ti" in C major (1234567).

Where "FA" (4) and "Ti" (7) are partial sounds.

There are two parts.

Namely "reducing FA" (B4) and "reducing Ti" (B7).

A six-tone scale is any one of five "notes" plus four "partials"
