- Maestoso - All[egr]o con fuoco
- Allegro molto
|Year/Date of Composition
||A Monsieur J. Delsart
||Cello and piano
apparently according to some reference sources, composed in 1897 (Boëllmann's last year) as well as published then though I am not sure of their evidence (his letters?...) - would also be good to find out if Delsart premiered the work for instance and with what pianist (the composer?) and when.
