B. Instrumental
Three violin concertos and one for two violins; known only from the wonderful clavier versions.
Most of the first movement of the A major sonata for clavier and flute which was written in the spare staves at the bottom of a larger score. Some of these have been cut off.
V.—Arrangements of Works by other Composers
Arrangements for harpsichord alone of 16 concertos, generally described as by Vivaldi, but including several by other composers.
4 Vivaldi concertos arranged for organ.
Many of these arrangements contain much original matter, such as entirely new slow movements, large cadenzas, &c.
Concerto in A minor for 4 claviers and orchestra, from Vivaldi's B minor concerto for 4 violins. This, though the most faithful to its original, is the richest and most Bach-like of all these arrangements, and is well worth performing in public.
2 sonatas from the Hortus Musicus of Reinken, arranged for clavier. (The ends of the slow movements are Bach.)
Finishing touches to cantatas by his uncle Johann Ludwig Bach. Also a very characteristic complete "Christe eleison" inserted in Kyrie of Johann Ludwig's.
