Concerto for two harpsichords in C minor, BWV 1060

While the extant 18th-century manuscripts present the concerto in a form for two harpsichords and strings, the assumption that it originated as concerto for violin and oboe has become widely accepted since the late 19th century.[2][3][4] The precise date for this earlier concerto is unknown, but it is believed to have been in existence from the early 1720s.[5] The version for two harpsichords likely originated in or around 1736.[6] A broader estimate for the time of origin of the version for two harpsichords is 1735–1740.[7]

1. Allegro	2. Adagio	3. Allegro

The concerto is scored for two harpsichords (cembalo concertato I and II), two violin parts (violin I and II), viola and basso continuo.[4] The difference in texture and figuration of both solo instruments is clearest in the outer Allegro movements.[1][3] In these movements, the melody lines of the cembalo II part are generally more lyrical and less agile than those of the cembalo I part.[1][3] The Adagio middle movement, where the melody lines of both solo instruments imitate one another without distinction in texture and figuration, has been likened to the middle movement of Bach's double violin concerto, BWV 1043.[1][7][8]

In his early 19th-century Bach biography, Johann Nikolaus Forkel described the concerto as "very old", with which he probably meant he found its style antiquated.[10][11][12] The concerto was published in 1848, edited by Friedrich Konrad Griepenkerl.[13][14]

In the 1874 preface to the Bach Gesellschaft edition of the concerto for two harpsichords, Wilhelm Rust had suggested that the original version of the concerto would have been for two violins.[1][15][16] In 1886 Woldemar Voigt wrote that the original instrument for the part of the second harpsichord was more likely an oboe, and that the original of the concerto could almost certainly be identified with a lost concerto for oboe and violin mentioned in a 1764 Breitkopf catalogue.[1][15][17][7]
