Pirastro Obligato Rosin

Obligato Rosin is specifically optimized for low- and medium-tension synthetic core strings, such as Pirastro’s Obligato series. It is designed to produce a mellow, rounded sound with minimal scratching. This provides excellent grip and a smooth bow response, helping you achieve a rich, warm tone without excessive surface noise. If you need help choosing the right rosin for your setup, a Sweetwater Sales Engineer is always available to assist.

This rosin is ideal for violinists, violists, and cellists who use low- to medium-tension synthetic strings and want to emphasize warmth and clarity. While it’s a perfect match for the Obligato string line, its balanced grip makes it a versatile choice for any player looking to reduce harshness in their sound. Whether you are practicing at home or performing on stage, this rosin helps maintain consistent playability across various environments.

To apply, gently swipe the rosin cake across the bow hair from frog to tip. A unique feature of Obligato Rosin is its hard plastic grip, which allows you to apply the rosin easily without getting dust on your fingers. Because it is optimized for synthetic strings, a few light passes are usually enough to provide the necessary friction. If you have questions about bow maintenance, Sweetwater’s educational guides and how-tos offer great tips for keeping your gear in top shape.

While specifically optimized for low- and medium-tension synthetic strings, Obligato Rosin can be used with gut or steel strings as well. However, players using high-tension steel strings might prefer a harder rosin, while those using pure gut might want something with more "bite." It’s a great middle-ground option for many orchestral musicians. Plus, with Sweetwater’s fast, free shipping, you can get the right rosin delivered quickly to keep your rehearsals on track.

If you notice excessive dust, try using less rosin or cleaning your strings with a soft, dry cloth after playing. If the rosin cake surface becomes smooth and loses its grip, you can lightly score the top with a clean abrasive to refresh it. If you're still having trouble getting the right "bite" from your bow, our live expert support can help troubleshoot your setup to ensure you're getting the best performance possible.
