Pirastro Obligato Viola G String, Silver-Wound Synthetic, 4/4 - Heavy

Pirastro Obligato Viola G String

The Pirastro Obligato Viola G String combines a synthetic multifilament core with silver winding for 4/4 violas. Soft, medium, and strong gauges offer three published tension levels. All versions use a ball-end attachment, letting players compare gauge options while retaining the same core material, winding, and fitting.

Choose this silver-wound synthetic viola string when replacing a worn G or reviewing your instrument's lower-register balance. Soft provides the lowest published tension, medium sits between the alternatives, and strong provides the highest. For a familiar replacement, match the gauge on your current packaging. When considering a change, compare the figures below with your playing preferences and instrument setup before selecting a replacement viola G string.

Pirastro assigns distinct manufacturer article numbers and peg-end identification colors to the options, giving performers, teachers, and instrument technicians practical ordering references. Weich means soft, Mittel means medium, and Stark means strong. Confirm the 4/4 designation and ball-fitting compatibility before installation. Record the selected article number so future orders identify your preferred gauge and packaging format clearly.
