The Sonata No 1 in G Minor is part of the sonatas and partitas for solo violin (BWV 1001–1006), a set of six works composed by Johann Sebastian Bach. The set was completed by 1720 but was not published until 1802 by Nikolaus Simrock in Bonn. Even after publication, it was largely ignored until the celebrated violinist Joseph Joachim started performing these works. Today, Bach’s Sonatas and Partitas are an essential part of the violin repertoire, and they are frequently performed and recorded. – Julian Bream
