The manufacturer Thomastik Peter Infeld called his eponymous string a revolution of total timbre for the discerning cello player. 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 cello playing. The set is composed as follows:

- A- and D string : solid carbonsteel core wound with multialloy wire
- G and C string : spiral core wound with tungsten/chrome wire
