Pirastro 1BCC Obligato Cello C String, Tungsten-Wound, 4/4, Medium

Pirastro Obligato Cello C String

The Pirastro Obligato Cello C String combines a synthetic-fiber core with tungsten winding for 4/4 cellos. It comes in medium gauge with a ball-end attachment and a published tension of 27.8 pounds. Manufacturer article 431420 identifies this individual replacement for the lowest string in a standard cello setup.

Choose this tungsten-wound cello C string when replacing a worn string or reviewing your instrument's lower-register balance. An individual replacement lets you retain your preferred A, D, and G strings while assessing the C separately. For rehearsal preparation, recital planning, or regular practice, match the size, gauge, and attachment to your instrument. Check your current packaging when reordering a familiar configuration.

Pirastro's published construction details and identification colors give performers, teachers, and instrument technicians clear reference points for selection. Violet identifies the peg end, while rust red and black identify the tailpiece end. Keep the manufacturer number with your instrument records to simplify future replacement orders. Confirm the 4/4 designation and ball-fitting compatibility before installation, particularly when maintaining a mixed string setup.
