My teacher put some powder on his hands for friction to rub a metal rod, and it made a high pitched sound. Can someone explain scientifically how he did it?

Valveless orchestral horns from the late 18th and early 19th century were generally able to equip all crooks from C alto down to B flat basso, but there are a few examples of higher and lower horn crooks (Mozart’s 19th symphony called for high Eb horns, and supposedly there are a few A basso horn parts in existence.) Is there any evidence as to what the absolute highest and lowest natural horn crooks EVER called for in classical music are?
