||Vier Stücke für Fagott und Cello
||4 Pieces for Bassoon and Cello
If these are the same 4 pieces as on a Gasparo LP/CD, they're Moderato - Andante - Allegretto - Allegro (and the notes say - paraphrasing - These works can be performed with the parts exchanged (the cello part played by bassoon and vice versa).). The finale doesn't sound much like a set of brief variations nor the 2nd movement like a compact duet fugue, but will have another listen.)
