Pirastro Evah Pirazzi Gold Viola 425021 is a professional medium-tension four-string set for 4/4 viola. Combining synthetic-core D, G and C strings with a steel A string, this configuration delivers a rich tonal palette, broad dynamic range and responsive bow control.
Sound and playing characteristics
Evah Pirazzi Gold strings offer a brilliant, refined tone with rich overtones, strong projection and a distinctive resonant quality. They are intended for players seeking expressive tonal flexibility in solo and ensemble performance.
The strings respond readily to changes in bow speed and pressure, supporting delicate piano passages and powerful forte playing. Pirastro also highlights their short break-in period and excellent tuning stability.
Standard 425021 set configuration
The D and G strings have synthetic cores with silver windings. The C string also has a synthetic core, combined with tungsten-silver winding to support a balanced transition across the lower strings.
425021 versus 425091: The 425021 has a synthetic-core C string with 5.6 kg tension. The 425091 features a steel rope-core C string with 6.5 kg tension, designed for a more direct response. The A, D and G strings are identical in both sets.

Selection and maintenance
The standard 425021 set is an excellent choice for violists seeking a rich, balanced lower register with a synthetic-core C string. For a more immediate C-string response, consider the 425091 set. After playing, remove rosin dust with a soft, dry cloth.
