Experience a brand new version of Bach’s BWV 1020 like never before - a new arrangement that now reimagines this great piece for two soloists instead of one. The added second part, composed in true Bachian-inspired contrapuntal style, breathes fresh life into this Baroque gem, doubling the dialogue, depth, and delight.

It should be noted that this piece is surrounded by a persistent mystery around who actually wrote it - Johann Sebastian Bach (J.S. Bach) or his son, Carl Philipp Emanuel Bach (C.P.E. Bach). This composition is stylistically lighter and more galant than most of J.S. Bach's authenticated chamber works, leading to questions about its origin.

Why J.S. Bach Might Be the Author:

1. BWV number: The sonata was originally included in the Bach-Werke-Verzeichnis (BWV), the thematic catalogue of J.S. Bach’s works.
2. Some early manuscripts attributed it to "Bach" without specifying which one.
3. It's housed among collections associated with J.S. Bach’s circle.

Why C.P.E. Bach Is Now Often Considered the True Composer:

1. Style: The piece is highly galant—a lighter, more elegant style that aligns closely with C.P.E.
2. Bach’s musical language, rather than the complex counterpoint associated with J.S. Bach.
3. Manuscript evidence: Surviving copies of the sonata are mostly in the hand of C.P.E. Bach or linked to his circle.
4. No autograph manuscript by J.S. Bach has ever been found for this piece.
5. The sonata appears in some catalogs or sources labeled as Wq 80 or H.542.5, which are C.P.E. Bach's own cataloging systems (by Wotquenne and Helm, respectively).
6. Most scholars now attribute BWV 1020 to C.P.E. Bach, and many modern recordings and performances reflect this view. However, since the BWV catalog traditionally included it under J.S. Bach, the BWV number is still commonly used.
