Violin construction and mechanics four open strings, usually tuned to G, D, A, and E. The strings run from a tailpiece attached to the base, across a wooden bridge, continue towards the neck of the instrument running parallel to the fingerboard, and connect to the pegbox located at the very top of the violin. They are wound around four tuning pegs that are mounted sideways through holes in the pegbox. The bridge helps to hold the strings in place, while the pegs maintain the tension necessary to produce vibration. Strings were first made of sheep's intestines (called "catgut"), stretched, dried and twisted. Contrary to
Claviharp Claviharp The claviharp is a 19th-century musical instrument that combined a harp with a keyboard. J. C. Dietz invented the instrument in 1813 CE. His grandfather was one of the first upright piano manufacturers. Struck by what he saw as difficulties and defects of the harp, in 1810, he built an "instrument à cordes pincées à clavier", which connected a keyboard to the harp strings. He made the instrument to address limitations of the harp—susceptibility of catgut strings to atmospheric change, inconsistency of sound as finger motion varies, limited diatonic scale (without pedals), and lack of dampers.
