TNH-3T, hard tension, is a classical half set made up of D'Addario's Titanium trebles, preferred for their bright and projecting tone. Pro-Arté Titanium strings are crafted from a dense monofilament material that has an attractive, translucent purple hue. Titanium strings have a polished, smooth feel similar to nylon, but with a slightly brighter tone and increased projection. As a result, the Titanium treble Strings may be substituted for current guitar strings with little player acclimation. Each half set contains 3 treble strings in a convenient resealable pouch.
