Violin of scordatura in classical music is Camille Saint-Saëns' "Danse Macabre", where the solo violin's E string is tuned down to E to impart an eerie dissonance to the composition. Other examples are the third movement of "Contrasts", by Béla Bartók, where the E string is tuned down to E and the G tuned to a G, and the Mystery Sonatas by Biber, in which each movement has different scordatura tuning. In Indian classical music and Indian light music, the violin is likely to be tuned to D–A–D–A in the South Indian style. As there is no concept of absolute pitch
String (structure) playability. The invention of wound strings, such as nylon covered in wound metal, was a crucial step in string instrument technology, because a metal-wound string can produce a lower pitch than a catgut string of similar thickness. This enabled stringed instruments to be made with less thick bass strings. On string instruments that the player plucks or bows directly (e.g., double bass), this enabled instrument makers to use thinner strings for the lowest-pitched strings, which made the lower-pitch strings easier to play. On stringed instruments in which the player presses a keyboard, causing a mechanism to strike the strings, such
