Detail 01
3/4 size
Cut for a 3/4 cello's shorter scale. A 4/4 string leaves too much length and seats badly at the peg.

D'AddarioPrelude Cello A String 3/4 Size
Independent shopping perspective
The Korena take
Single A string for a 3/4 cello. Replacement for the string that breaks most often on student instruments.
Strong match
Who this is for
- Replacing a snapped A on a 3/4 student cello
- Keeping a spare in the case for lessons and recitals
- School programs stocking the most-broken string
Consider the trade-offs
When to look elsewhere
- Anyone on a 4/4 cello — wrong scale length
- Players wanting warmth and complexity from the top string
- Someone whose whole set is worn — buy a set
What matters in use
The specifications, translated
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 02
A string
Highest and thinnest of the four. It takes the most bow pressure and breaks more often than the rest.
Detail 03
Steel core
Comes to pitch fast and stays there. Resists the humidity swings a case going between home and school puts it through.
Detail 04
Prelude line
D'Addario's student cello string. Priority is durability and tuning stability over tonal depth.
Detail 05
Single string, not a set
The other three stay as-is. A fresh A next to three worn strings will sound brighter and louder.
Final check
Know before you order
- 01Confirm the cello is 3/4 — a 4/4 string will not seat correctly
- 02A fine tuner on the A is close to essential with steel core
- 03Smooth the bridge and nut grooves; a rough groove is what snapped the last one
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Why does the A string keep breaking?
Usually a sharp edge in the bridge or nut groove, or a burr on the fine tuner. Smooth the groove with a pencil or fine file before fitting a new string.
02Will a 4/4 A string work on my 3/4 cello?
It can be forced on, but the winding lands in the wrong place at the peg and nut, which hurts tuning stability and shortens string life.
03How do I know if my cello is 3/4?
Measure the back, from the top edge to the bottom, excluding the neck. A 3/4 cello runs roughly 27 to 28 inches; a 4/4 runs about 30.
04Should I loosen the other strings when changing the A?
No. Leave them at pitch so the bridge and soundpost stay loaded. Change one string at a time.
