D'Addario H513 3/4M G 3/4 Cello Strings

Helicore Cello G String — Stranded Steel Core for 3/4 Scale Cellos

The D'Addario Helicore Cello Single G String is a replacement string designed specifically for 3/4 size cellos, offering cellists a reliable upgrade or replacement option that maintains consistent tonal character. Built around a stranded steel core rather than a traditional solid gut or synthetic core, this string delivers the quick response and short break-in time that working players appreciate when swapping strings between rehearsals or performances. The nickel winding applied over the multi-wire steel core produces a clear, articulate voice with enough warmth to blend in ensemble settings while retaining the definition needed for solo passages.

Medium tension strikes a practical balance between bow resistance and fingerboard pressure, making the G string comfortable for extended practice sessions without sacrificing projection in larger rooms. D'Addario engineers and crafts every Helicore string in their New York facilities, applying the same in-house quality control that defines the broader Helicore family of orchestral strings. The ball end fitting allows straightforward installation on standard cello tailpieces, and the string is calibrated to sit properly on a 3/4 scale instrument's bridge and nut geometry.

Who This String Is For

The Helicore Cello Single G String suits cellists who need a dependable replacement string for a 3/4 scale instrument, whether the original G has worn out or the player wants to refresh the instrument's voice with a stranded steel core option. Advancing students moving from beginner-level strings will find the medium tension approachable, while intermediate and returning players benefit from the quick bow response and stable tuning that stranded steel cores provide. Teachers outfitting student cellos for school programs or rental fleets will appreciate the consistent quality that comes from D'Addario's domestic manufacturing process.

Players who prefer a brighter, more focused tone on the G string — particularly those working on solo repertoire or chamber music where the G line needs to cut through — will find this string's nickel winding and steel core combination well suited to their needs. The medium tension also works well for cellists who play both arco and pizzicato, since stranded steel cores tend to respond well to both bowing techniques. For anyone seeking a single-string replacement that matches the broader Helicore family's tonal character on a 3/4 cello, this G string delivers a focused, reliable voice.
