How does string tension influence the sound?
In general, it can be said that the higher the tension, the louder the sound. Unfortunately, high tension has a number of disadvantages. First of all, it makes playability and response worse. This is manifested mostly in the softer dynamic ranges and higher positions. Moreover, with increasing tension, the number of overtones in the sound decreases; the sound becomes rather strong, but does not project well. When the tension is too low, the sound is thin and sharp, lacking a robust core.
Of course, strength of sound and responsiveness are also influenced by factors related to the structure of strings and the materials used in making them. The tensions of our strings are very similar to those found in other high quality synthetic and gut strings . However, we seek to achieve lower tensions whenever possible. The tensions of some of our E strings (Karneol, Brilliant) are a little higher because of the complexity and softness of the soprano register. E strings with higher tensions tend to whistle on some instruments. To guarantee you will have no problems with a whistling E string, use our non-whistling "Ametyst Eď.
