D'Addario titanium single strings are designed for the classical guitarist, specifically to flamenco, folk and other "non-classical" musicians.

D'Addario T2 Titanium Guitar Strings are crafted from a dense monofilament material that has an attractive, translucent purple hue. T2 strings have a polished, smooth feel similar to nylon, but with a slightly brighter tone and increased projection. As a result, the T2 Titanium Treble Strings may be substituted for current guitar strings with little player acclimation.
