Perpetual Edition are the most power-packed strings in the Pirastro program. Tone by tone the shine of this string radiates into the room without sounding metallic or sharp. Like having a palette in their hands, the Perpetual Edition provides the musician with every tonal color from a focused bright sound to a room filling warmth. With their sonority, volume, and flexibility the new Perpetual Edition fulfills the players’ desire for projection in an impressive way while maintaining an inspiring light playability. The Perpetual Edition strings offer an exceptionally nice bow resistance which results in a very fast and direct response especially on the lower strings.
