You see, the snake is staring at the head of the flute and moving the snake head with the movement of the flute. The snake is not interested in music at all, but only in moving targets.

In addition, there are "shots of snakes attacking people during flute playing". I've seen it in exploration. This is because the "piper" is not skilled enough to attract the snake's attention to the tip of the flute, so that the snake's head shakes with the flute, and the snake pays attention to his body movements, which mistakenly makes the snake feel that danger is approaching, and then carries out self-defense attacks.

You know cobras are actually very reluctant to attack people. Secreting and storing venom in the body is a very physical activity. Venom is precious, and it will only be used when it preys or thinks its life is threatened.
