Does a violinist bow have horsehair on it?

Yes, a violinist's bow typically has horsehair stretched between the tip and the frog. The horsehair is sourced from the tails of horses and is specially prepared and shaped to provide the necessary friction for playing a violin. The quality and condition of the horsehair can significantly impact the tone and playability of the violin, and professional violinists often pay close attention to the selection and maintenance of their bow hair.
