As the title suggests, this work appears to be (my Dutch is not at all fantastic) a collection of pieces dedicated to flowers to whit: La Rose, Les Penées, Les Giroflées, L'Iris, L'Oeillet, Les Anemones, Les Marguerites, La Julienne, Le Jasmin, Les Oreilles D'Ours, Les Primes Veres, Le Muguet, L'Amarante, La Tulipe, La Jacinte, La Violette, Les Ranoncules, Le Narcisse, La Tubéreuse, La Jonquille, Le Chèvre-Feuille, La Grenade, Le Tricolor, Le Volubilis. As you see, dear surfer, a veritable horticultural show!
Delavigne dedicated this work to the Duchess of Biron and it was intended to played by musettes (a French bellows-blown bagpipe) or vielles (hurdy-gurdies) accompanied by violins or flutes. This type of music was very popular in France and must have sounded very interesting. In fact this work provides me with some justification of trying out music for concertina (with which one can easily make a drone effect) and recorder.
I was introduced to this item by Stephan Schrader some time in the mid 1980's who liked using this work for recorder duos.
