Classical guitar strings, traditionally made from nylon or carbon fiber, produce warm, articulate tones suited for fingerstyle and classical performance. Before modern nylon, gut strings were the standard. Leading brands include Savarez (Cristal Corum and Alliance series), D’Addario (Pro Arte and XT), Hannabach (815 series), and Augustine (Classic and Imperial sets). Normal tension strings offer a balanced feel and sustain, while high-tension strings provide more projection and attack. Carbon strings, such as Savarez Alliance, offer brighter tones for modern players. These strings are essential for classical, flamenco, and fingerstyle guitarists seeking tonal purity and responsiveness.
