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
Violin technique other strings are not so equipped. The A string is tuned first to a reference pitch source such as a tuning fork or, in most orchestras, the oboe, typically to 440 Hz, although some orchestras tune to another standard A such as 442, or even as high as 445 or 446 Hz to produce a brighter sound. Early music groups interested in authentic performance may use a lower standard A. When playing with a fixed-pitch instrument such as a piano or accordion, the violinist must tune to accommodate that instrument. The other strings are then tuned to the A in
