The "Five Tones", refers to the five levels of the ancient Chinese pentatonic scale, namely Gong, Shang, Jue, Zhi and Yu. After the Tang Dynasty, it was also known as He, Si, Yi, Chi and Gong. Equivalent to 1, 2, 3, 5, and 6 in modern simplified music notation.
 

The giant panda Zhi Yu takes his name from the last two sounds of the ancient Chinese five tones.
