Walther erroneously attributes the original concerto to Signor Meck, but modern research has confirmed that the concerto was actually a violin concerto composed by Vivaldi.
The concerto contains three movements. An opening Allegro movement alternates ritornello passages for manuals and pedal with solo interludes for manuals only. The second movement is an Adagio for manuals only. The third movement is an Allegro in 3/4 time with a similar form to the first movement.
This is the end of the concerto transcriptions by Walther.
