The core is the most central part of the string that runs from end to end. Most strings fall into one of four core categories: solid steel, stranded steel, synthetic or gut.
SOLID STEEL CORE strings feature a single steel wire running throughout the entire length of the string. Examples: Prelude (except Double Bass), Kaplan Viola A, Kaplan Cello A/D.
STRANDED STEEL CORE strings have a core made out of thin steel wires braided together in a rope-like formation. Examples: Prelude Double Bass, Helicore, some Kaplan Viola and Cello, Kaplan Double Bass.
SYNTHETIC CORE strings feature a core made from synthetic (manmade) fibres. Examples: Kaplan Violin/Viola Amo and Vivo, Zyex, Pro·Arté.
GUT CORE strings, the oldest known type of string material, are made from the small intestines of sheep and cows.
