Scordatura tuning was mainly popular in the Baroque period from 1600-1750. Composers such as Heinrich Biber often used it. He composed a group of sonatas for violin and accompaniment called the "Rosary Sonatas". In each sonata the violin is tuned in a different way. In Sonata XI (called "Resurrection") he even asks the violinist to make the two middle strings cross over between the bridge and the tailpiece so that the violin is tuned to two Gs and two Ds.
