This Trio Sonata was previously thought to have been by Graun. The title page suggests that only the figures in the Bass part were added by Graun.
Although F# minor is an extremely strange key for oboe, it is likely that this Sonata was written for the Berlin Oboist Johann Christian Jacobi (1719-1784). Marpurg, in "Historisch-Kritische Beyträge zur Aufnahme der Musik" describes him as a "worthy oboist" and also says that Janitsch composed Trios, Quadros and Concerti in the usual and unusual keys. A note dedicating a Trio Sonata in D-flat major (!) to Jacobi can be seen here. There are also other Trios by Janitsch for oboe in A major, A-flat major, E-flat minor (lost), B minor as well as several other in more "usual" keys.
