After the Grand Duchy was established in 1815, interest in music slowly developed across the country, initially with patriotic music played by military bands. In 1842, the Luxembourg Army Band known as the "Musique militaries grand-ducale" was found in Echternach with some 24 musicians from the battalion stationed there. In 1852, the "Société philharmonique" was founded in Ettelbrück by the local priest J. B. Victor Müllendorf with the objective of "supporting all types of vocal and instrumental music". On the occasion of the first train from Luxembourg to Thionville on 4 October 1859, the national poet Michel Lentz wrote the words and music for "De Feierwon", a patriotic song with the famous line "Mir welle bleiwe wat mir sin" (We want to remain as we are).
