This is white horsehair for a erhu bow. Length: Approximately 79cm, from Mongolia. Thread for securing the hair is also included. Both ends are processed for easy attachment to the bow, so replacement should be relatively easy. Once the hair is tensioned and rosined, you can at least produce sound. But just because you can produce sound doesn't mean it's okay! As you play, the surface of the hair wears down from friction with the strings, gradually losing its grip. Also, as you tension the hair and play, it gradually loses its elasticity. Yes, without realizing it, your bow might be transforming into a "difficult-to-play bow." It's hard to notice the timing when you're using it every day. If you thought "Ah!" during the following self-check, replacing the hair will significantly improve your playing! 31.1-inch super bow hair made from unbleached Mongolian horse tail hair.
