Violin Strings 【Peter Infeld】 Peter Infeld - Thomastik - Used for about a month. Please understand that this is a used item, so only those who understand this are welcome to purchase. They have a strong tension, and the tone is bright and clear. They also have a good volume, and you can feel a solid sound projection when playing in a hall, with good response in articulation. You can feel the above advantages right after stringing them. Even when playing close to the bridge (ponticello), they produce a very strong and supple tone, even with a slight rasp. Depending on the instrument, they can withstand the pressure of the bow, where usually the sound would break up immediately. Like other nylon strings, the tuning is also stable, making them all-around strings.
