Composed by Johann Sebastian Bach (1.685-1.750) URTEXT Adaptation for viola, edited and transcribed by Roisber Narvaez Throughout history numerous musicians have had discrepancies between arcades, articulations, notation and phrasing for the execution of the six Solo Cello Suites BWV 1007-1012 by Johann Sebastian Bach who wrote around 1720 during his performance as a chapel master in the court of Coethen. It is quite certain that the Suites were intended to form a second part of a collection or a larger complex of which the first part is composed of the work Sonatas and Partitas for solo violin, BWV 1001-1006, dated in 1720 with the Bach's own hand. The absence of an autograph copy of the composer does not make it possible to have an accurate answer on how the work should be interpreted accurately, caused by the inequality between the four existing manuscripts:1: a copy prepared by his wife Anna Magdalena between 1727 and 1731.2: a copy prepared by Johann Peter Kellner in 1726.3: a copy prepared by two anonymous written in the middle of the 18th century.4: an anonymous copy dating from the end of the 18th century.This has given players the opportunity to contribute musical ideas about the Suites. However, this version presented for Viola, is based on the manuscript of Anna Magdalena Bach 1727-1731.
