"Scordatura" notation was first used in the late seventeenth century as a way to quickly read music for violin with altered tunings. It was a natural choice for viola d'amore and other stringed instruments not tuned in the usual fifths, especially those whose intervals between strings are not uniform across their range. Heinrich Ignaz Franz Biber, Antonio Vivaldi and Johann Joseph Vilsmayr (a student of Biber), among others, wrote pieces for violin with one or more strings retuned to notes other than the usual fifths. Given that the viola d’amore was usually played by violinists and that many different tunings were used, scordatura notation made it easier for a violinist to read the music.
