The harpsichord was a common instrument in the 1930's, but never as popular as string or wind instruments in the concerto role in the orchestra, probably due to its relative lack of volume in an orchestral setting. In this context, harpsichords were more usually employed as a continuo instrument, playing a harmonised bass part in nearly all orchestral music, the player often also directing the orchestra. Bach's Brandenburg Concerto No.5 in D major, BWV 1050, may be the first work in which the harpsichord appears as a concerto soloist. In this piece, its usual continuo role is alternated with prominent solo obbligato episodes in all three movements. In the first movement the harpsichord, after rapid scales up and down the length of its range, embarks on a solo cadenza which lasts for 3–4 minutes, while the orchestra is silent.
The concerto for solo harpsichord
It was also popular at this time to adapt Italian concertos for other instruments for solo harpsichord —which Bach did with many of Vivaldi's concertos. The concerto transcriptions Bach made for harpsichord are listed as BWV 972–987. Bach's Italian concertoBWV 971 is in this transcription style, though it was written as an original piece for harpsichord. by Christian Petzold was published in 1729. In 1738 published a similar concerto in G minor. Bach also composed a concerto for two harpsichords without orchestral accompaniment, BWV 1061a, which is the early version of the concerto for two harpsichords and string orchestra, BWV 1061.
The new harpsichord concerto
With the harpsichord revival in the 20th century, harpsichordists commissioned new pieces for the new 'revival' instrument: Wanda Landowska commissioned concerti from Francis Poulenc and Manuel de Falla. Though the 'revival instruments' have now fallen out of favour, concerti continue to be written for harpsichord, though are now more likely to be played on a copy of a historical instrument, perhaps with a small orchestra or some amplification to ensure it can be well heard.
