Obligato Viola Strings – Warm and Brilliant Sound

The Pirastro Obligato viola strings are among the most popular synthetic strings for viola. Their core is made of a specially developed synthetic multifilament fibre, created in collaboration with Pirastro’s exclusive supplier. This results in a string with exceptional tonal flexibility and warmth.

Obligato strings are especially valued for their rich overtone spectrum, combining warmth with radiant brilliance. They respond reliably across all dynamic levels, offer a wide range of volume, and maintain a focused, balanced tone at all times.

Another key strength is their tuning stability and resistance to humidity and temperature changes, which makes them highly reliable for orchestral use, ensemble playing, and solo performance.

Available in different tensions, Obligato viola strings offer options that meet the needs of professionals as well as advanced students seeking both power and expressive nuance.
