Detail 01
4/4 size
Cut for full-size cellos only. A 3/4 instrument will have far too much slack and will not tune reliably.

Independent shopping perspective
A single C string for full-size cellos, medium gauge, from D'Addario's student line. For school players and teachers replacing a worn low string.

What matters in use
Catalog numbers tell only part of the story. These are the details most likely to change how this product feels, sounds, or fits into a setup.
Detail 01
Cut for full-size cellos only. A 3/4 instrument will have far too much slack and will not tune reliably.
Detail 02
Standard tension. Sits in the middle for bow response and left-hand feel, and matches most stock setups.
Detail 03
Lowest and thickest string on the cello. Takes the longest to settle after fitting and is slowest to speak under the bow.
Detail 04
Built for durability and stable tuning in classroom conditions rather than tonal nuance.
Detail 05
Fine for a single replacement. Fitting one new string next to three old ones leaves an uneven set.
Final check
Product questions
Straight answers to the questions shoppers most often ask about this product.
No. This is cut for 4/4 instruments. A 3/4 cello needs a 3/4 string or it will not hold tension correctly.
No, it is the C string alone. A complete change means buying G, D and A as well.
New strings need playing in. The C is the thickest, so it takes the longest to settle and speak clearly, often a week of regular use.
Yes. Medium is the standard tension most cellos are set up for, so it needs no adjustment to bridge or soundpost.
