Bach – Concerto for Two Keyboards – Khatia and Gvantsa Buniatishvili
The well-known Double Violin Concerto in D minor, BWV 1043 is the basis of the transcription for the Concerto for two keyboards. It was transposed down a tone to allow the top note E6 to be reached as D6, the common top limit on harpsichords of the time. Most of Johann Sebastian Bach‘s harpsichord concertos (with the exception of the 5th Brandenburg Concerto) are thought to be arrangements made from earlier concertos for melodic instruments probably written in Köthen. – Khatia Buniatishvili
