A String Thomastik Alphayue 4/4 for Violin
The A is the string your fingers touch most, and Alphayue builds it accordingly: a synthetic core with an aluminum winding and a ball end. Aluminum is not a cost saving here but physics — it is the lightest of the working winding metals, adding almost no mass, which is why the middle register stays clear instead of thickening up. Tension is 5.5 kp (12.1 lb), second in the set after the E. One gauge, medium. Thomastik describes the range as a balance of brilliance and warmth, and the A is where that balance is easiest to hear.
🏆 SoundsGood — genuine Thomastik-Infeld strings only, made in Vienna.
Aluminum Keeps the Middle Clear
The winding decides how much mass a string carries, and mass decides how fast it responds. Light aluminum gives the A an agile, clear tone: in scales and double stops the voice does not go muddy, and crossing from E to A does not sound like jumping from metal into cloth. For a player still building intonation that matters — a transparent middle does not hide a sour note, it shows it.
The String That Wears Out Next After the E
The A carries the main workload of the left hand: first position, vibrato, constant contact with fingers and the moisture that comes with them. Thomastik states corrosion resistance and an exceptionally long life-span for Alphayue, and on the A that service life turns into money — you are not replacing a whole set because one voice is finished. Buying a single AL02 is a normal, planned replacement.
5.5 kp — the Middle Rung of the Tension Ladder
In the AL100 set the load steps down evenly: 7.9 kp on the E, 5.5 kp on the A, 4.5 kp on both D and G. The A holds the middle rung, which is why moving the bow from the first string to the second feels natural — no extra pressure, no letting go. Fitting a single AL02 into a living Alphayue set keeps that ladder intact.

Frequently Asked Questions
What are this string's specifications?
Alphayue 4/4 A, article AL02: synthetic core, aluminum winding, ball end, tension 5.5 kp (12.1 lb), medium gauge, 32.5 cm vibrating length.
What end type does it have?
A ball end, like the D and G of the Alphayue range. In this series only the E (AL01) has a removable ball.
Is there a silver-wound Alphayue A?
No. In the Alphayue range the A comes in one version only — aluminum wound on a synthetic core, article AL02. Silver in this series sits on the G (AL04).
Is this the same A that comes in the AL100 set?
Yes. In the AL100 set it works with the E (AL01, 7.9 kp), D (AL03, 4.5 kp) and G (AL04, 4.5 kp), 22.4 kp in total.
What if my violin is a smaller size?
You need the matching article: on 1/2 size that is AL02 1/2 at 5.1 kp, also aluminum wound. Note that on the smallest 1/16 size the Alphayue A is Monel wound rather than aluminum.
Are these genuine Thomastik strings?
Yes. SoundsGood supplies only genuine Thomastik-Infeld product in official packaging marked with article numbers.
