Thomastik Peter Infeld 4/4 violin string set (E-platinum)

Peter Infeld is the top synthetic line from the Viennese house of Thomastik-Infeld, and the maker states its purpose plainly: a "substantial amount of sound colors, easy to control", suitable for experienced amateurs up to the highest professional level. Set PI100 is built around the platinum-plated E, PI01PT — 8.3 kp, a stainless steel core, removable ball end. The A, D and G sit on a synthetic multifilament core with one aluminium winding (5.6 kp) and two silver ones (4.8 and 4.7 kp), and together the four voices come to 23.4 kp (51.6 lb) over a 32.5 cm vibrating length. The silver on the lower strings is not there for density alone: Thomastik deliberately uses "a special silver winding to produce a specific bow noise, which makes your sound shine all the way to the farthest corner of the room". The platinum E is the maker's recommendation for soloists — it "has a clear & focused sound" and is extremely corrosion-resistant if you tend to sweat.

How the 23.4 kp Are Split Across Four Voices

The E takes more than a third of the total — 8.3 kp against 5.6 on the A and under 5 on the D and G. That is not a lopsided design but the way an even feel is achieved: a thin steel monofilament would collapse under bow pressure in the upper positions without that load, while synthetic A, D and G hold their shape at far lower tension. From there the fall is gentle — 5.6, 4.8, 4.7 kp — so crossing from string to string does not retrain your left hand, and in chords no single voice jumps out in front. It matters for the instrument too: 23.4 kp is a normal modern-synthetic load on the bridge, with no excess strain on the body.

Silver on D and G Buys Projection, Not Just a Denser Bottom

Thomastik says outright that the silver winding in this line exists for a "specific bow noise" — the breathy component in the attack that you barely notice up close but that carries the tone across a hall. In practice, the back rows hear more than volume: the start of every note stays legible at distance. The G, wound with "specially processed silver", adds winding mass on top of that, so the bottom comes out compact and supportive rather than boomy, and it does not fall apart at full forte.

The Platinum E: Who It Is For and What It Costs

PI01PT is the soloist's choice: the maker calls its sound clear and focused, and the platinum plating makes the string extremely corrosion-resistant, so a sweaty hand does not eat it in a fortnight. The trade-off is stated just as openly — the platinum E whistles a bit more easily than the tin-plated one. Since all three E strings in the line — platinum PI01PT, tin-plated PI01SN and gold-plated PI01AU — carry the same 8.3 kp, you can swap it in this set at any point without rebalancing the other three.

The pack holds four strings — E PI01PT, A PI02, D PI03A and G PI04 — each carrying its own Thomastik article number. It covers a complete restring with nothing to buy separately.

Who It's For

A set for the soloist who needs a clear, focused E and projection to spare in a large hall; for the orchestral and chamber player who wants a wide palette of colours without losing control; and for the experienced amateur who has outgrown mid-range synthetics and is ready for professional-level response.
