Still, I should not have dwelt so long on the doings of the Musical Ressource were it not that it was the germ of, or at least gave the impulse to, even more influential associations and institutions that were subsequently founded with a view to the wider diffusion and better cultivation of the musical art in Poland.

After the battle of Jena the French were not long in making their appearance in Warsaw, whereby an end was put to Prussia's rule there, and her officials were sent about, or rather sent out of, their business.

Thus the Musical Ressource lost many of its members, Hoffmann and Mosqua among others.

Still, it survived, and was reconstructed with more national elements.

In Frederick Augustus of Saxony's reign it is said to have been transformed into a school of singing.
The year 1815 brought into existence two musical institutions that deserve to be noticed--society for the cultivation of church music, which met at the College of the Pianists, and had at its head Count Zabiello as president and Elsner as conductor; and an association, organised by the last-named musician, and presided over by the Princess Sophia Zamoyska, which aimed at the advancement of the musical art in Poland, and provided for the education of music teachers for schools, organists for churches, and singers for the stage.
