Pirastro 1BCD Obligato Cello D String, Chrome Steel-Wound, 4/4, Medium

Pirastro Obligato Cello D String

The Pirastro Obligato Cello D String combines a synthetic-fiber core with chrome steel winding for 4/4 cellos. It comes in medium gauge with a ball-end attachment and a published tension of 31.3 pounds. Manufacturer article 431220 identifies this individual replacement for the D position in your string setup.

Choose this synthetic-core cello D string when replacing a worn string or reviewing your instrument's string balance. An individual replacement lets you retain your preferred A, G, and C strings while assessing the D separately. For rehearsal preparation, recital programs, or regular practice, confirm the size, gauge, and fitting before ordering. Match your existing article number when replacing a familiar configuration.

Pirastro's published material specifications and identification colors give performers, teachers, and instrument technicians clear reference points for selection. Rust red 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. Check compatibility with your cello's tailpiece hardware before installation, particularly when maintaining a mixed string setup.
