The sonatas and partitas for solo violin (BWV 1001–1006) are a set of six works composed by Johann Sebastian Bach. They are sometimes referred to in English as the sonatas and partias for solo violin in accordance with Bach's headings in the autograph manuscript: "Partia" (plural "Partien") was commonly used in German-speaking regions during Bach's time, whereas the Italian "partita" was introduced to this set in the 1879 Bach Gesellschaft edition, having become standard by that time. The set consists of three sonatas da chiesa in four movements and three partitas (or partias) in dance-form movements. The 2nd Partita is widely known for its Chaconne, considered one of the most masterful and expressive works ever written for solo violin.
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.
Some believe the literal meaning of the title "sei solo" when read as German rather than Italian words (Be alone [imperative]) is an intentional reference to the recent sudden death of his wife. This theory is popular among musicians but not among Bach scholars, though the exceptional indication of the year of completion on the title page does seem to indicate a payment of homage to his wife.
