Our music for this week is the Keyboard Concerto No. 4 in A Major by Johann Sebastian Bach. It is performed by David Fung and the Melbourne Chamber Orchestra.
When Bach wrote this concerto in 1721, the piano (or, in his day, the harpsichord) was a relatively new discovery. It is therefore tempting to think that the concerto was written as a way to showcase the range and versatility of the keyboard. However, Bach originally wrote this concerto for the oboe. When the piano burst onto the musical scene in the early 1700’s, he transposed the oboe concerto into a piano part to try to capitalize on the public frenzy over the instrument.
As is typical of most concerti from the Baroque era, this concerto contains three movements. The first and third movements are faster, while the second movement is more restrained. Those of you who have been with us for a while may notice that the piano solo part is not as prominent as the solo parts from Classical or Romantic-era concerti. In the Baroque era, composers sought to emphasize the ways in which the soloist wove in and out of the accompaniment parts, but later eras sought to feature the soloist in a more virtuosic setting. It is interesting to see that modern concerti (composed after the year 2000) are trending back toward a more Bach-like blended concerto style.
