The manufacturer Thomastik Peter Infeld called his eponymous string a revolution of total timbre for the discerning violinist. The strings of Peter Infeld (PI) indeed produce a rich spectrum of timbres and a powerful/elegant sound within a large dynamic range. All this with a direct response and good tunability. The strings feel relatively soft, which can result in an optimal interpretation of the violin playing. The following strings are available:

• E string, carbon steel/tin-plated;
• E string, stainless steel/gold-plated;
• E string, stainless steel/platinum-plated (in set);
• A string, synthetic core with aluminum winding;
• D string, synthetic core with aluminum or silver winding;
• D string, synthetic core with silver winding;
• G string, synthetic core with silver winding;
• All strings have a ball, except the E strings, which have a removable ball=loop.
