I had a student this week ask me what Rosin was, and what it was made of. Though I knew it was made of tree sap, I realized that I didn’t know much about the making of rosin. Rosin is one of the most important accessories for violinsts (and violists–we won’t leave them out), because rosin provides traction for the bow to glide on the violin’s strings. I found some really helpful resources the making of rosin (with pictures!), what rosin to choose when starting, what the difference is between light and dark rosin, and more!
