Tonica Violin Strings Features - Tonica strings have a core made from nylon. - They produce a lively well-rounded sound, perfectly balanced across all four strings. - Responding instantly to any bowing style, they reward both player and listener with an open and direct sound. - With substantially reduced background 'hiss', players can sustain a more even tone helping to achieve smoother string crossings. - With a highly responsive left hand feel, Tonica strings remain very easy to play all the way up to the highest positions. - Projection and brilliance have been upgraded. However, this excess does not mean that the Tonica has lost its warmth. - Playing pianissimo has considerably improved. - All bow strokes are possible resulting in smooth crossings from one note to another. - Easy right hand articulation and tone attack. - Due to their medium string tension Tonica strings are suitable for all instruments. - Insensitive to variations in temperature and humidity The set E-Aluminum contains: E-steel wound with aluminum, A-aluminum, D- and G-silver.
